ASTM 4320H/JIS SNCM420/DIN (B29)20NiCrMo7
Is a commonly used alloy carburizing steel, carburizing after surface have very high hardness, wear resistance
and contact fatigue strength, and the heart part still retain good toughness, able to withstand high impact load.
Mainly used for railway bearing impact resistant, wear resistant parts.
