Product Description

Product Description

 

SNCM420(AISI 4320) Wear Resistant Bearing Steel

Alloy steels comprise different kinds of steels having compositions exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels. 

SNCM420 alloy steel has high toughness and strength. It contains low carbon content to achieve good welding characteristics.
