gb t 3077 40mn2 steel chemical element

  • gb t 3077 40mn2 steel chemical element

  • 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 gb t 3077 40mn2 steel chemical element alloy steel gb t 3077 40mn2 steel chemical element 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.
