Abstract

Duplex stainless steels represent a promising alternative when aggressive/marine atmospheres characterize the component's final application. In this frame, grades with higher Pitting Resistance Equivalent Number (40 or above) may be used in hydrogen sulphide and chloride-containing environments. UNS 32760 Duplex Stainless Steel powders have been obtained through close-coupled gas atomization, starting from wrought bars. The paper analyses the effect of different parameters on the characteristics of the final powder in terms of granulometry, morphology, microstructure, and chemical composition (compared to the starting material), also taking into account light elements such as N, O, H, C, and S.
