BS S156 in the British Standard Aerospace Series is a 4% Ni-Cr-Mo case-hardening steel with a tensile strength of 1,320-1,520 MPa.
DELIVERY CONDITION
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 carburising, hardening and tempering.
SUPPLY
BS S156 aerospace steel bar is supplied in black bar, bright bar and forgings. The supply condition of the alloy is normalised and softened. In fabrication, parts produced will need to be supplied in the heat treated condition - this consists of carburising, hardening and tempering.
