SUJ2 Bearing Steel Bar - Spheroidize Annealed
SUJ2 bearing steels is a high-carbon chromium alloy steel, which, because of its versatility, is used in a variety of mechanical applications. In the annealed condition this steel is comparatively easy to machine, yet very high hardness and abrasion resistance can be developed by heat treatment to make the steel particularly suitable for applications requiring extreme wear resistance. In addition,SUJ2 bearing steels can be heat treated to high levels of tensile strength and fatigue strength.
