MATERIAL-B4B

This type of steel is a martensitic stainless steel with the highest electrical conductivity among processed martensitic stainless steels. It’s a hardening martensitic stainless steel designed for service temperatures of up to 650° C. This quality develops high mechanical properties through thermal treatment and offers good resistance to oxidation and resizing. Typical applications include buckets and blades in steam turbines, high-temperature bolting and valve lining
