F44is an austenitic stainless steel used in seawater and other aggressive chloride-bearing media. This grade has excellent resistance to pitting and crevice corrosion, high resistance to general corrosion and stress corrosion cracking, with a higher strength than conventional austenitic stainless steels, and good weldability.
We holdF44round bar stock from 12.7mm to 189mm, although we can supply additional sizes on competitive lead times.
