What is the heat treatment for 25Cr2MoVA material?

25Cr2MoVA material is a medium carbon heat resistant steel. Both strength and toughness are high. When it is lower than 500 ℃, the high temperature performance is good, there is no tendency of hot brittleness, hardenability is good, cutting machinability is acceptable, cold deformation plasticity is moderate, and weldability is poor. Generally, 25Cr2MoVA steel can be used in the quenched and tempered state, can also be used after normalizing and high temperature tempering.
