High Carbon Chromium Bearing Rod/Carbonized Bearing Rod/Stainless Steel Bearing Rod

Overviews:

Bearing Steel GCR15 wire rod is generally used for bearing needle and ball production. To meet the requirements of strength and toughness, fatigue resistance, and wear resistance, high quality is required. Bearing steel has high carbon content and carbides will be precipitated in different degrees during continuous casting. Some researches show that the homogeneity of the carbide has a great influence on the service life of the bearing. To eliminate the above defects, higher heating temperature and longer holding time are needed before rolling bearing steel to eliminate carbide inhomogeneity. Bearing steel has high hardness, tensile strength, contact fatigue strength, wear resistance, and considerable toughness, which meets the requirements of corrosion resistance and high-temperature resistance under certain conditions.

Main uses:

Bearing steel hot-rolled wire rod is mainly used for manufacturing ball bearings (ball) and so on.
