Duplex UNS S31803 / S32205 is an austenitic-ferritic stainless steel used for corrosive environments and is capable of resisting localized corrosion such as pitting, crevice corrosion and stress corrosion cracking. The austenitic-ferritic chemical composition results in mechanical properties that are able to cope with high stress conditions where the use of ordinary austenitic stainless steel would result in mechanical failure.
