Gb 20crh Steel Optimized Organizational State - China

The first quenching temperature is set at 880℃, aiming to make the internal structure of GB 20CrH steel undergo phase transformation and form high-strength structures such as martensite; The second quenching temperature range is 780℃～820℃, further refining the grains of GB 20CrH steel and improving the hardness; the subsequent water cooling or oil cooling process quickly cools the steel and fixes its high-temperature structure state.

The tempering treatment is carried out at 200℃, and the quenching stress is eliminated through slow cooling or air cooling, improving the toughness and stability of GB 20CrH steel.

This series of heat treatment processes makes the metallographic structure of the steel reach the best state, laying a solid foundation for subsequent processing and use.
