BS S154 Steel Bar

Aerospace grade steel.

BS S154 is an aerospace-grade steel alloy that includes nickel, chromium, and molybdenum.

We stock BS S154 steel bars to the British aerospace standard, which perform well at elevated temperatures.

BS S154 is an aerospace-grade steel alloy that includes nickel, chromium, and molybdenum additions. The alloy offers high tensile and yield strength (the tensile strength being 880 - 1080 N/mm²). The high strength and toughness of the material are typical in large sections. The alloy is available in bars and forgings and offers good creep resistance, good toughness and performs well in high-temperature environments.

For General Engineering

826M31 (EN25) is the equivalent to BS S154. The material is regarded as a good general engineering alloy that may be utilised in numerous applications such as the production of crankshafts, aerospace components, and high-strength bolts.
