stainless steel; corrosion resistant steel; ferrite
The material 1.4509 is a ferritic chromium steel with good corrosion resistance and medium mechanical properties. In contrast to the austenitic stainless steels, this grade has excellent resistance to stress corrosion cracking, which is why it is mainly used in exhaust systems.
