Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This S700MC high strength car beam steel alloy steel S700MC high strength car beam steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used S700MC high strength car beam steel, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

The difference between S700MC high strength car beam steel, 10# seamless steel pipe and 20# seamless steel pipe:
1. Chemical composition
Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25
2. Mechanical properties
10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
