Steel sheet art. 20 thickness 25mm - high-quality unalloyed steel, which is used for the manufacture of metal structures and products operating at temperatures from -40 to 450 ° C. Hot-rolled and forged sections from steel 20 are produced in accordance with the requirements of the DSTU 7809 and GOST 1050 standards
Steel 20 is used in construction, mechanical engineering, the production of boilers and vessels, the manufacture of heating elements for various purposes. Unalloyed high-quality structural steel 20 in the form of sheet and section steel is used for the manufacture of elements of welded structures, pipelines, manifolds, bearing shells, slings and other products. Shafts, gears, worms, friction discs, axles, spindles, pins, sprockets, studs and other products made of steel 20 after chemical-thermal treatment (carburizing, nitriding, nitrocarburizing, etc.) acquire high surface hardness and wear resistance with low core strength.
The composition of steel grade 20 is very diverse, because it contains carbon, manganese, silicon, copper, arsenic, nickel, phosphorus and sulfur. In essence, this type of steel is a very interesting mixture, which contains ferrite and pearlite. During heat treatment, the structure of the material can be changed to batch martensite. It is worth noting that these transformations of the structure will lead to the fact that the strength of the steel will increase, and its plasticity, on the contrary, will decrease. If steel 20 is subjected to heat treatment, then it can be used in the manufacture of special products of the hardware type.
