Material Application
Japanese JIS standard SUJ2 high carbon chromium bearing steel, corresponding to the national standard GCr15, SUJ2 high carbon chromium bearing steel, can be fully hardened, the hardness can reach HRC58-61, has the wear resistance of the bearing, also strengthens the rigidity, workability Good, and can be directly processed and shaped, using mold times 2-3 times higher than SKD-61 (HRC52) full hardware. During quenching and tempering, the size does not change much, and fatigue resistance is quite good.
