Abstract

Influence of Cu on microstructure, mechanical and corrosion properties of a new family of Cr22 duplex stainless steels (DSSs) is investigated. The results indicate that Cu can greatly increase volume fraction of austenite and enhance elongation and corrosion resistance. The yield stress and tensile strength of new economical Cr22 DSSs reach approximately 490 and 750 MPa respectively. The mechanical properties and corrosion resistance of the new economical Cr22 DSSs are better than those of AISI304.

Key words： nickelsaving duplex stainless steels; pitting corrosion resistance; tensile properties
