The main JIS standard alloy steel material for structure Dec 13, 2018 · SNCM420 is also a carburized steel. Its mechanical properties are similar as SNCM220, both has relatively high hardness, abrasion resistance and contact fatigue strength after carburizing on the surface. SNCM420 is mainly used as railway bearing, transmission shaft, gear, screw, tool parts and other parts that can withstand impact and wear.SNCM420 steel - Steel gradesTool & Die Steels Inc.
