Studies and Research on the Corrosion Behaviour in a 3.5% NaCl Solution of Sintered 316 Stainless Steels

Abstract

Products made from austenitic 316 stainless steels obtained through powder metallurgy technologies are used in many applications across various industrial fields due to their resistance to corrosion from air, water, and different acids. They are also non-magnetic, possess good mechanical properties at both low and high temperatures, offer good creep resistance, and have good weldability. This paper presents a series of experimental studies on the corrosion behaviour of sintered austenitic 316 stainless steels in a 3.5% NaCl solution. The different behaviours observed can be attributed to varying compaction pressures and can be improved by reducing surface roughness, increasing chemical and structural homogeneity, and by alloying.
