3% Chromium-Molybdenum Nitriding Steel
BS S132 in the British Standard Aerospace Series is a 3% Cr-Mo-V nitriding steel offering a tensile strength of 1,320-1,470 MPa. (excellent hardenability for high core strength) and develops a hard wear resistant case after surface treatment.
The alloy is usually produced by single melting in air followed by electroslag refining (ESR) but is also available as a vacuum arc remelted version. Bars and, where applicable, forgings are subjected to ultrasonic examination. Bars are usually supplied bright in the softened condition. Final heat treatment consists of hardening at 950°C (oil quench) followed by tempering at not less than 600°C (air cool).
BS S132 aerospace steel bar is supplied in the bright and softened condition and is used in complex components including gearboxes and crankshafts.
