3,high strength and hardenability

ASTM 8620H/JIS SNCM220/DIN (B28)20NiCrMo2/GB G20CrNiMo

ASTM8620H is a commonly used alloy carburizing steel, equivalent to the GB/T5216-2004 of our country in

the standard 20CrN iMoH, Cr-N i-Mo is widely used in surface hardening steel carburizing and carbonitriding.

Carburizing surface has very high hardness, wear resistance and contact fatigue strength, and the heart part

still retain good toughness, able to withstand high impact load. ASTM8620H is mainly used for automobile

bearing impact resistant, wear resistant parts materials.
