Why is Stainless Steel Corrosion Resistant? - Industrial

Stainless steel must have at least 10.5% chromium in order for the passive layer to form.The more chromium that is added,the more stable the passive layer becomes,and the better the corrosion resistance.Other elements such as nickel,manganese,and molybdenum can be added to enhance stainless steel corrosion resistance.What is the best technique for improving wear resistance To improve the wear resistance of 0Crl3Ni4Mo martensite stainless steel,the tempered steel was treated by salt bath nitriding at 450,480 and 510 for 2 hours.What Makes Stainless Steel Corrosion Resistant?
