Application Field: GCr15 ball bearing steel is used to manufacture high-quality cutting tools such as scissors, nozzles, bearings, etc.
Features: In domestic stainless steel grades, 440C boasts high hardness. It is primarily used for manufacturing bearing components that operate in corrosive environments and under strong oxidative atmospheres without lubrication. 440C has good high-temperature dimensional stability, thus it can also be used as a corrosion-resistant high-temperature bearing steel.
Grade: G10-G500
