Corrosion properties of Stainless steel

Chromium content in austenitic stainless steel 304 and 316L can increase the resistance to pitting corrosion through the formation of passive layer on the surface of metal. The corrosion properties of these stainless steels in the chemical mediums with different concentrations are determined throu...
