Application Field: GCr15 bearing steel balls are used to manufacture high-quality tools such as scissors, nozzles, bearings, etc.
Features: 440C boasts high hardness among domestic stainless steel grades. It is primarily used for manufacturing bearing parts that operate in corrosive environments and under lubrication-free, strongly oxidizing atmospheres. 440C offers good high-temperature dimensional stability, making it also suitable for use as corrosion-resistant high-temperature bearing steel.
Grade: G10-G500
Hardness HRC: 58-61
