Product Description

Product Description

 

ASTM 52100 Bearing Steel

52100 is a high-performance bearing steel. A deep-hardening alloy steel used in high-stress applications where good rolling contact fatigue strength is required at operating temperatures below 400°F (204°C). This grade is produced by the vacuum-arc remelting process and offers greatly improved cleanliness and internal soundness over conventionally air melted bearing quality SAE 52100 steel. This alloy can also be made available as a vacuum induction melted plus vacuum arc remelted (VIM-VAR) product.
