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 a633 grc structural steel plate vs sa573 alloy steel a633 grc structural steel plate vs sa573 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.

The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex, which mainly involves the thermal expansion coefficient, specific heat capacity coefficient, thermal diffusion coefficient, yield limit, elastic modulus and hardening index. Under the same process conditions, the greater the specific heat and thermal conductivity of the composite a633 grc structural steel plate vs sa573, wear-resistant steel plate, the less obvious the temperature gradient in the forming process, and the smaller the bending angle produced.
