BS S132 Steel Bar

Excellent hardenability.


BS S132 is a nitriding steel alloy that develops a hard, wear-resistant case after surface treatment.

BS S132 nitriding steel bars contain chrome, molybdenum and vanadium for high mechanical strength.


BS S132 is a nitriding steel alloy that develops a hard, wear-resistant case after surface treatment. The result is a high tensile alloy that is highly suitable for applications such as engine shafts, crankshafts and gearboxes. The alloy benefits from excellent hardenability for high core strength, providing a tensile strength of 1,320 - 1,470 MPa. The material produced by single melting in air and subsequently followed by ESR (electroslag refining). However, there is also a vacuum arc remelted version of this alloy. BS S132 bars and forgings should be subjected to ultrasonic testing where possible, and the material is typically supplied in bright and softened condition.


Commercial Applications

Applications include gearboxes, shafts, turbine/engine parts and motorsport components.
