Application Fields: Gcr15 bearing steel ball can be used to manufacture high-quality cutting tools such as scissors, nozzles, bearings, etc.
Features: Among domestic stainless steel grades, 440C boasts high hardness. It is primarily used for manufacturing bearing parts that operate in corrosive environments and under strong oxidation atmospheres without lubrication. 440C exhibits good high-temperature dimensional stability, thus it can also be used as a corrosion-resistant high-temperature bearing steel.
