Stainless Steel - Austenitic - 2S130D - AMS5646

2S130D - AMS5646

S130 is an austenitic chromium-nickel stainless steel. The additional niobium stabilises the alloy overcoming the risk of corrosion common to other stainless steel grades exposed to high welding temperatures. The steel is produced by an electric melting process and also conforms to the requirements of BS S100. The alloy is non-magnetic and cannot be hardened by heat treatment. Typical applications are within the aerospace industry where corrosive conditions are severe, such as aircraft exhaust stacks, manifolds and ring collectors.
