Описание
SUJ2 steel is a Japanese JIS standard high carbon chromium bearing steel grade. After heat treatment, it has high and uniform hardness, good dimensional stability and corrosion resistance, but the weldability is poor. SUJ2 material is used to make various bearing rings and rolling elements, such as steel balls, tapered rollers, cylindrical rollers, spherical rollers, needle rollers, etc. It can also be used to manufacture molds, precision measuring tools, etc. The chemical composition of SUJ2 bearing steel are displayed in the following table.
