Steel BSt3ps

Characteristics of steel grade VSt3sp

VSt3sp - Structural carbon steel of ordinary quality, welds well, welding is carried out without heating and without subsequent heat treatment, welding methods: manual arc welding, automatic submerged arc welding and gas protection, KTS, ESW. For thicknesses greater than 36 millimeters, heating and subsequent heat treatment are recommended; it is prone to flake sensitivity, and there is no tendency to temper brittleness. Machinability by cutting in the hot-rolled state at HB 124 σB = 400 MPa Kυ hard alloy. = 1.8 and Kυ b.st. = 1.6, has found its application in load-bearing elements of welded and non-welded structures and parts operating at positive temperatures. Shaped and sheet products (5th category) - for load-bearing elements of welded structures operating under variable loads: with a thickness of rolled products up to 25 mm in the temperature range from -40 to +425 ° C; for rolled products with thickness over 25 mm - from -20 to +425 °C, subject to delivery with guaranteed weldability. Forging at temperatures from 1300 to 750 0C, cooling is carried out in air. Calm steel has a dense structure and good mechanical properties. It is less prone to negative reactions to welding heat and to aging. The features of a homogeneous microstructure give the alloy maximum corrosion resistance and ductility.

Interpretation of steel grade VSt3sp

Interpretation of steel: The letter B at the beginning denotes a group of steel that determines the tensile strength criteria for the chemical composition. Steel, in the name starting with the letter B, the strength is 20-30 MPa lower than steel of group A. The following letters St. indicate that the steel is of ordinary quality, although most steels are high quality. The numbers from 0 to 6 are the conventional brand number depending on the chemical composition and mechanical properties. Typically, the higher the number, the more carbon and the greater the strength. In our case, 3 indicates the carbon content in the alloy is 0.14–0.22%. The letters after the brand number indicate the degree of deoxidation: cn - calm.

The letters after the brand number indicate the degree of deoxidation: cn - calm. In terms of price, calm steels have become more expensive than semi-calm and boiling steels. Mild steel is steel obtained as a result of deoxidation. It is obtained by deoxidation with aluminum, manganese and silicon. The level of oxygen in it is so reduced that during metal processing no reaction occurs between carbon and oxygen, and the presence of non-metallic slags and their inclusion is reduced to a minimum. Calm steel has a dense structure and good mechanical properties. It is less prone to negative reactions to welding heat and to aging. The features of a homogeneous microstructure give the alloy maximum corrosion resistance and ductility.
