P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel. P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min.); Elongation ≥25%; Brinell hardness ≤105 ~ 140. S315MC steel for cold forming parts, P235GH steel chemical composition (mass fraction,%): ≤0.16 C; ≤0.35 Si; 0.60 ~ 1.20 Mn; ≤0.025 P; ≤0.010 S; ≤0.30 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; ≤0.020 Al; ≤0.03 Ti.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S315MC steel for cold forming parts quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S315MC steel for cold forming parts quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
