Through Hardenable Steel

BS S155 in the British Standard Aerospace Series is a Nickel-Silicon–Chromium–Molybdenum–Vanadium through hardening steel with a tensile strength of 1,900-2,100 MPa.

The material is manufactured by consumable electrode vacuum arc remelting (VAR). Bars, and where practicable, forgings, are subjected to ultrasonic examination. Bars and forgings are supplied in the normalised and softened condition. Parts produced from bar and forgings are required to be supplied in the finally heat treated condition which consists of hardening followed by oil quenching and tempering followed by air cooling.

Key Features:

BS S155 aerospace steel bar is supplied in black bar for machining and in forgings. The alloy is normally subjected to ultrasonic inspection before supply. It is used widely in high technology applications such as aerospace and motorsport.
