Product Description
Grade S32205 is a duplex stainless steel characterized by a roughly equal mixture of austenite and ferrite phases. This microstructure grants it superior strength and excellent resistance to stress corrosion cracking, pitting, and crevice corrosion compared to standard austenitic stainless steels. S32205 offers improved corrosion resistance and mechanical properties.
