BS S130 Stainless Steel Bar

Non-magnetic, austenitic stainless steel.


BS S130 is an austenitic 18% chromium and 9% nickelwhich is stabilised with niobium.

We stock BS S130 austenitic stainless steel bars which offers good resistance to atmospheric attack.


BS S130 is an austenitic 18% chromium and 9% nickel and a BS aerospace grade stainless steel. The alloy is niobium stabilised to overcome the risk of intergranular corrosion, which is typical of certain stainless steels after exposure to temperatures of 430 to 820°C.

The material is non-magnetic and cannot be hardened by subsequent heat treatment. With good formability and cold working characteristics, BS S130 offers a machinability rating of approximately 36% (with 1212 rated at 100%). The addition of niobium prevents sensitisation (weld decay) and may be welded by most standard methods except forge and hammer welding. Post weld heat treatment is not required with this alloy.


Corrosion Resistance

With high corrosion resistance, the alloy also offers good oxidation resistance. The material is particularly suited to welded structures and finds use in aerospace components and fasteners, nuclear components and food processing applications.
