BS S145 Stainless Bars

BS S145 is a precipitation-hardened stainless steel and a British Standard aerospace grade. The alloy provides high strength and medium to good corrosion resistance. BS S145 offers a chemical composition identical to BS S143 and BS S144 but differs because of greater tensile strength achieved after additional heat treatment.

Stock Availability

We stock and supply BS S145 stainless steel bars in solution-tempered condition and various incremental sizes to suit your engineering requirements. We stock alloys to much closer sizes, which often removes the need for further machining, saving you time and money.

Commercial Applications

As a high-strength aerospace alloy, BS S145 finds use in producing mechanical components in aircraft, nuclear parts and defence applications. Although defined as an aerospace-grade material, the alloy offers usage in a broad range of general engineering applications.
