Products Description:
AISI 8620 alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardenss is 28-34 HRc. AISI 8620 steel Annealing delivery hardenss less than 250HB.
AISI 8620 Alloy structural steel properties is a Nickel chromium molybdenum alloy steel specification. 8620 With a lower carbon content range, So AISI 8620 alloy steel have good weldability. AISI 8620 Steel is equivalent to Din 21NiCrMo2 | W-Nr 1.6523, GB 20CrNiMo, BS 805M20, NF 20NCD2,JIS SNCM220 Steel. Most applications can replace each others

Heat treatment Related
Slowly heated to 850 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 8620 alloy steel will get MAX 250 HB (Brinell hardness).
Heated slowly to 880-920°C, Then after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
