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
