BS S145 Stainless Steel Bar

Precipitation hardened stainless steel.

BS S145 offers a chemical composition identical to BS S143 and BS S144 but offers greater tensile strength.

Our stock of BS S145 stainless steel bars are suitable for aerospace applications.

BS S145 is a precipitation-hardening 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; this will undoubtedly save you time and money.
