Stainless steel 08Х 18Н 10Т: characteristics, application, analogues

History of discovery

Today it is difficult to imagine a world without numerous inventions.
Many of them were made by accident. This is how stainless steel appeared. The first historical mention of this metal can be found in the records of Harry Brierley. This metallurgist researcher in 1912 took an order from one of the weapons companies to find an effective way to extend the service life of gun barrels. The practitioner began to work in his usual style - he began mixing different components. The man tested the finished alloys for heat resistance and durability. If the indicators were low, the blanks were sent to a landfill. One of the details stood out among all with its brilliance. After a detailed study of the analysis, scientists found that the alloy consists of several elements:

• iron - 85.3%;
• chromium - 12.8%;
• manganese - 0.44%;
• carbon - 0.24%;
• silicon - 0.2%.

Not all researchers give the lead in the discovery of the stainless flock to Harry Brierley. Some believe that stainless steel was discovered by Pierre Berthier, a French mining engineer. He discovered that certain compounds of iron and chromium, which can be found in nature, stand out for their high acid resistance. He was the first to suggest making dishes and cutlery from them.

Receiving technology

When processing parts, it is important to obtain the desired mechanical properties. Their combination is obtained thanks to two components:

• chemical composition;
• thermal and/or mechanical treatment - steel 08Х18Н10Т is no exception.

Stainless steel has features that combine plasticity, which makes it possible to roll out metal with a thickness of less than 1 mm, and strength, which is sufficient for the manufacture of critical utilities and parts operating under high pressure in highly aggressive environments.

Decoding stamps

The marking of alloy steels consists of letters and numbers. At the beginning there is a two-digit number that characterizes the amount of carbon in hundredths of a percent. The following are letters of the Russian alphabet, denoting a specific element:

• X – chromium;
• N – nickel,
• T – titanium;
• B – tungsten;
• G – manganese;
• M – molybdenum;
• D – copper.

After the letter designation of the alloying element in the decoding there is a number indicating its content in stainless steel, rounded to the nearest whole percent. If there is no such figure, then the additive in the alloy is in the range of 1-1.5%.

Types of stainless steel and its classification

The entire variety of anti-corrosion steel types is divided into 5 large groups. The basis for this division is the microstructure of the material. Of these, representatives of the following 3 groups are most often found:

1. Martensitic steel is distinguished by the letter “C” in the marking. It acquires its properties not only due to its composition, but also as a result of hardening and tempering. Applicable in the production of cutlery and cutting tools. Slightly magnetized, has increased hardness.
2. Ferritic alloy is softer than martensitic alloy. Also endowed with magnetic properties. Its designation contains the letter “F”.
3. Austenitic steel, containing 15-20% Cr and 5-15% Ni, is not magnetized and has the highest resistance to corrosion. Denoted by the letter "A". Steel grades from this group are most common in industrial production, as well as in the manufacture of hardware and fastening devices.

In turn, austenitic alloys are divided into 5 classes, additionally indicated by a digital value:

• A1 is the least resistant to corrosion due to the sulfur contained in the chemical composition. Used for the manufacture of parts for mechanical and moving units.
• A2 is steel that is resistant to moisture, but is not suitable for work in environments containing acids, alkalis, chlorine and salts. Ecologically harmless, not magnetized, not subject to hardening. Excellent for the manufacture of all types of fasteners intended for use in non-aggressive conditions.
• A3 - similar in properties to class A2 steel. However, this metal better resists corrosion in high-temperature environments, due to the stabilization of the alloy with niobium, titanium or tantalum.
• A4 - differs from A2 steel in the presence of molybdenum in an amount of 2-3%. This small additive gives the metal high resistance to acids, alkalis, and salts. Can operate in low temperatures, down to -60°C. A4 fasteners are intended for the construction of bridges and coastal structures. It is used in shipbuilding, chemical and oil and gas enterprises.
• A5 is steel stabilized with titanium, which makes it highly resistant to corrosion at high temperatures. Other technical characteristics are similar to class A4.

This is interesting: Hole diameter for metric threads: with and without a table.
In different countries, fasteners are produced according to different standards. In Russia these are GOST standards, in Germany – DIN, in the USA – AISI, in Europe – EN and international ISO. Many fasteners manufactured according to the standards of different countries are considered analogues. However, this is not entirely correct, since small differences still exist, if only due to the inconsistency of measurement systems. Therefore, it is better to entrust the replacement of fasteners when assembling structures that differ from those indicated in the drawings to specialists.

Types of stainless steel corrosion

Despite the name, high-alloy steel is still susceptible to corrosion if it is not used properly and is poorly maintained. The following types of environmental damage are possible for stainless steel:

1. Crevice type corrosion occurs where a stainless steel element works in tandem with another material. An aggressive substance may leak between them, and oxygen access will stop. The oxide film is destroyed without restoration, and the metal begins to rust.
2. Pitting corrosion, which affects stainless steel products with a matte surface. Damage begins with microscopic scratches or cracks. This kind of corrosion can be “cured” by high-quality grinding and polishing.
3. Contact corrosion occurs when high-alloy parts are combined with low-carbon steel elements.

In welds, corrosion can be caused as a result of overheating or poor-quality processing of the joint.

Chemical composition

Steel is an alloy of carbon and iron, in which the iron atoms are located in a crystal lattice, and the remaining elements, depending on their size and behavior, change it. In terms of carbon concentration, steel 08Х18Н10Т is a highly alloyed carbon alloy. Where the main alloying elements are chromium, nickel and titanium.

The basic rule of metallurgy on which changes in strength are based is: “Distortion of the structural lattice increases strength.” Thus, a carbon atom, which has a size much smaller than an iron atom, penetrates into the crystal lattice and distorts it, giving it strength. Other elements that can replace iron atoms and exhibit properties characteristic of each of them also merge in the same way.

Chrome is the hardest metal in existence. At a concentration of more than 13% it imparts corrosion resistance. How does this happen. By reacting with an oxygen atom, chromium creates an oxide film only a few atoms in size. The oxides are not much larger in size than the chromium atom itself (unlike iron oxides, which have a 3-volume), so it creates a dense shell on the surface itself, preventing the penetration of oxygen and other gases. This protection works even when heated. If such a film is scratched, new oxides immediately form in its place. This process is called patenting.

In difficult temperature operating conditions, where steel experiences constant temperature loads, chromium carbides are formed along the grain boundaries, which leads to the destruction of the metal, i.e. intergranular corrosion. To eliminate this process, nickel is added to the alloy, which is an austenite stabilizer, preserving this structure at room temperature (for comparison: in conventional carbon steels, the temperature of transformation of austenite into more stable structures is 650-750 ºC).

Titanium is added to the alloy in an amount of 0.6% and contributes to the stability of 08Х18Н10Т in aggressive environments.

Purpose of stainless steels

Corrosion-resistant steel is an alloy that is resistant to corrosion. The chromium content in the chemical composition is 10.5-11%. Combining with oxygen, the component forms an oxide film. Having received minor mechanical damage, the protective barrier is able to recover.

Most of the alloy consists of iron. The addition of carbon up to 1.2% ensures tensile strength. To obtain other beneficial properties, alloying additives are added: titanium, phosphorus, molybdenum, sulfur, nickel, niobium, cobalt. One of the frequently used grades of stainless steel is 12x18n10t.

The disadvantages of stainless steel include high cost and poor machinability. The advantages are the following:

• resistance to corrosion;
• high strength, load resistance;
• good weldability;
• service life – 20-50 years;
• preservation of properties;
• resistance to aggressive environments;
• attractive appearance - does not require painting.

The listed characteristics ensure the use of stainless steels in a wide variety of areas. The material is used to produce pipeline fittings, cutlery, cars, airplanes, spaceships, medical instruments, etc. Among the areas of application:

• mechanical engineering;
• chemical, pulp and paper, food industry;
• architecture;
• electric power industry;
• aircraft manufacturing;
• medicine and healthcare.

Stainless steel piping parts

Weldability of steel 08Х18Н10

Metal can be welded using almost any modern method. Before welding, the alloy does not need to be heated, and after welding, the seams do not need to be heat treated. Some experts recommend additional annealing (as a preventive measure for intergranular corrosion); in this case, the alloy needs immediate cooling. The cooled seam should be treated with etching paste and cleaned of scale. The resulting seam is durable and corrosion resistant (due to the presence of nickel).

The main advantages of the alloy

Stainless steel grade 08Х18Н10Т is manufactured in accordance with the requirements of GOST 5632-72. It has high ductility, allowing it to easily produce thin-walled parts. When welding, it does not require preheating and subsequent cooling of the weld. The metal can be perfectly processed using any milling equipment.

Pots, pans and other utensils can be made from it. And due to the affordable price, the cost of such dishes turns out to be very affordable.

Which is better: carbon steel or stainless steel?

Stainless steel is used:

• in the energy and chemical industries when working with aggressive environments;
• in medicine, aircraft manufacturing, where durability and increased strength of instruments are required;
• in construction and other areas where the type of parts plays an important role.

Carbon steel is needed there:

• where a lot of durable material is required - for example, in the construction of pipelines;
• where there is no need for improved metal properties - in particular, in the production of small parts of mechanisms and tools.

The considered types of steel cannot be placed in the same row. Materials are selected based on the project budget and area of ​​application.

What is unique about stainless steels?

Stainless steel was patented in England in 1913. The author of this invention, which, without exaggeration, became the most important stage in the development of not only steel, but also other industries, is metallurgist Harry Brearley.

The addition of an element such as chromium to their chemical composition made it possible to endow ordinary steel alloys with unique characteristics and obtain corrosion-resistant steels from them.

It is chromium, which must be at least 10.5% in stainless steel alloys, that provides these materials with such characteristics as:

• exceptionally high corrosion resistance;
• very high strength;
• good weldability;
• ease of processing using cold deformation methods;
• long service life without loss of original characteristics;
• aesthetically attractive appearance of products made from alloys of this category.

Influence of alloying elements on the properties of steels

Stainless steels necessarily contain chromium and iron in their chemical composition. These elements complement each other, which is what gives these materials such unique characteristics. In particular, chromium, combining with oxygen, creates an oxide film on the surface of the stainless alloy, which becomes a reliable obstacle to corrosion processes.

In order to provide stainless steel with additional characteristics and significantly improve existing properties, alloying additives are introduced into its chemical composition - nickel, titanium, molybdenum, niobium, cobalt, etc. This alloying makes it possible to create various types of stainless steel alloys that differ from each other their characteristics and, accordingly, purpose.

We are already so accustomed to corrosion-resistant steel that we don’t even notice how much more comfortable our lives have become due to the presence of stainless steel in it.

Stainless steel contains carbon in its chemical composition, which gives it high hardness and strength. It should be noted that this chemical element is an essential component of any steel alloy and has a serious impact on its properties.

The unique characteristics of stainless steel make it possible to successfully use this metal in a variety of areas related to the operation of products and equipment in conditions of high humidity and constant exposure to aggressive environments. Stainless steels are actively used for the production of products for both industrial and household purposes. In particular, it is from this metal that cutlery and knives are most often made, elements of communications and enclosing structures, equipment parts, etc.

The most popular brands and areas of their application

To choose the right stainless steel for the manufacture of products for a specific purpose, you can use special reference books that list both all grades of such material and their main characteristics. Meanwhile, in each of these groups there are the most popular brands, which are most often chosen by the consumer. Let's list them.

• 10Х17Н13М2Т and 10Х17Н13М3Т are steels that are characterized by good weldability and excellent corrosion resistance. Thanks to these properties, stainless steel alloys of these grades are successfully used for the production of products that, during their operation, are constantly exposed to high temperatures and aggressive environments. The properties of steels of these grades are formed due to the presence in their chemical composition of the following elements: chromium (16–18%), molybdenum (2–3%), nickel (12–14%), carbon (0.1%), silicon (0 .8%), copper (0.3%), sulfur (0.02%), phosphorus (0.035%), manganese (2%), titanium (0.7%). If there is a need to select stainless steels of these grades, then you should keep in mind that their foreign analogues can also be purchased on the domestic market, namely: SUS316Ti (Japan), 316Ti (USA), OCr18Ni12Mo2Ti (China), Z6CNDN17-12 (France) ).
• 08Х18Н9 and 08Х18Н10 are stainless steel alloys from which pipes of both round and any other cross-section are made. These materials are used for the production of various structures used in the mechanical engineering and chemical industries, as well as for the production of pipeline elements and furnace devices. The chemical composition of these grades of steel contains the following elements: chromium (17–19%), carbon (0.8%), titanium (0.5%), nickel (8–10%).
• 10Х23Н18 - steel of this grade is characterized by a high content of nickel (17–20%) and chromium (22–25%), as well as manganese (2%) and silicon (1%) in its composition. This combination of elements gives the alloy the required characteristics and creates an increased tendency to temper brittleness. It should be noted that the alloy of this grade belongs to stainless steels of the heat-resistant category.
• 08Х18Н10Т - a stainless alloy of this brand is characterized by high resistance to oxidation processes, as well as good weldability, and to obtain a high-quality connection using this technology, the products do not need to be preheated, and they also do not require heat treatment after welding. To improve the strength characteristics of products made from such steel, they must be hardened, as specified in the relevant regulatory document.
• 06ХН28МДТ - an alloy of this grade is optimally suited for creating welded structures that will subsequently be used in aggressive environments. The chemical composition of this steel contains the following elements: chromium (22–25%), nickel (26–29%), copper (2.5–3.5%).
• 12Х18Н10Т – products made from steel of this grade are mainly used to equip enterprises in the chemical, pulp and paper, construction, food and fuel industries. This metal is characterized by thermal resistance, good impact strength and practicality of use.
