What is A815 S31803
Duplex stainless steels are extremely corrosion-resistant, work-hardenable alloys. Their microstructure consists of a mixture of austenitic and ferrite phases. Thus, duplex stainless steels display the properties of both austenitic and ferritic stainless steels. This combination of properties implies some compromises compared to pure austenitic and pure ferritic steel grades.
Duplex stainless steels are, in most cases, harder than ferritic stainless steels. The strength of duplex stainless steels can be twice that of austenitic stainless steels in some cases.
Although duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels.
