BS S154

Steel Bars

Aerospace steel bars with nickel, chromium and molybdenum.


BS S154 Steel Bar

Aerospace grade steel.

We stock BS S154 steel bars that conform to British aerospace standards and performs well at elevated temperatures.


BS S154 is an aerospace-grade steel alloy with nickel, chromium, and molybdenum additions. It offers high tensile and yield strength (880 - 1080 N/mm²), which is typical in large sections. The alloy is available in bars and forgings and offers good creep resistance, good toughness, and performance 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 crankshafts, aerospace components, and high-strength bolts.
