Description:
It is a medium-carbon and high-strength high-quality carbon structural steel. (Corresponding to Chinese brand: No. 50 steel )
Chemical composition content:
C:0.47-0.55 Si:0. 17-0.37 Mn:0.50-0.80 S:≤0.035 P:≤0.035 Cr:≤0.25 Mo:≤ 0.30 Cu:≤0.25
Depending on the scale of production, there are two methods of forging steel billets:free forging and die forging. Free forging is mostly used for small and medium-sized batch production, and die forging is used for large-scale mass production. According to different working conditions and usage requirements, different materials are selected and different heat treatment specifications (such as quenching and tempering, normalizing, quenching, etc.) are used to obtain a certain degree of strength, toughness and wear resistance.
