Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking including sulfide stress corrosion crackingpitting, crevice corrosion and high strength when compared with other stainless alloys. However, one thing is clear-materials are not added in these codes unless the parent specification requires tensile testing to ensure that the product being supplied actually meets the minimum mechanical properties upon which the design is based.
