The difference between duplex stainless steel and common stainless steel?

Duplex stainless steel stands out for its unique composition of both austenitic and ferritic phases – Ferrite being stronger. This combination results in a material that surpasses common stainless steel in terms of strength and corrosion resistance tolerance. Common stainless steel typically falls into the austenitic category. Duplex’s corrosion resistance and mechanical properties make it a preferred choice where common stainless steel may fall short.
