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.
AISI 8620 Steel Round Bar Sheet Plate, DIN 1.6523, JIS SNCM220
8620 steel has high hardenability without temper brittleness. It is also called DIN 1.6523 and JIS SNCM220 steel. It also has good weldability, little tendency to form cold cracks, and good machinability and cold strain plasticity. It is used to make gears, shafting, bolting, springs, hand tools and etc. 8620 steel round bar sheet plate properties and 8620 steel composition as below.
