S50C steel plate is a high-quality high-quality medium carbon steel. S stands for steel, which means iron, and 50 stands for carbon content of 0.50%. C represents carbon steel, which means that S50C is a carbon steel with a carbon content of 0.50%.Mechanical properties of S50C steel plate:Tensile strength σb (MPa): ≥630 (64); Yield strength σs (MPa): ≥375 (38); Elongation δ5 (%): ≥14; Reduction of area ψ (%): ≥40; Impact Work Akv (J): ≥31(4); Impact toughness value αkv (J/cm2): ≥39(4)Hardness: unheated, ≤241HB; annealed steel, ≤207HB
Phosphorus is a very harmful element in SA283 Gr D steel material properties steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of SA283 Gr D steel material properties steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
Quenching Improve the hardness of SA283 Gr D steel material properties steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of SA283 Gr D steel material properties steel and comprehensive mechanical properties.
