PRODUCT DETAILS
Product introduction
GB 20CrNiMo alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, and it belong to the high quality low carbon, low chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardenss is 28-34 HRC. GB 20CrNiMo steel Annealing delivery hardenss less than 250HB.
GB 20CrNiMo Alloy structural steel properties is a Nickel chromium molybdenum alloy steel specification. 20CrNiMo With a lower carbon content range, So GB 20CrNiMo steel have good weldability.

Heat treatment Related
- Annealing of 20CrNiMo Alloy structural steel
Slowly heated to 850 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 20CrNiMo alloy steel will get MAX 250 HB （Brinell hardness）.
- Hardening of 20CrNiMo Alloy structural steel
Heated slowly to 880-920°C, Then after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
