Description
SUJ2 Round Bar
SUJ2 Round Bar is Bearing Steel is the best product for bearings with high hardness and wear resistance. Evenly treated and high-quality chrome alloy steel to ensure optimal hardness and long service life.
SUJ2 Bearing Steel is one kind of special steel with features of high wear resistance and rolling fatigue strength. High-carbon chromium bearing steel, engineering steel and some types of stainless steel and heat resistant steel are used as materials of bearings and for other purposes.
JIS SUJ2 bearing steel is JIS standard Alloy Bearing steel, It belong to the high quality high carbon, alloy chromium,manganese steel.SUJ2 Steel properties is a chromium,manganese alloy steel specification. it is equivalent to AISI 52100, DIN 100Cr6, GB GCr15 steel. Most applications can replace each others.
