WebDec 27, 2024 · Though stainless steel doesn’t rust, in general, there are cases where rusting will happen. As mentioned above, stainless steel (used in jewelry) is an alloy of chromium, nickel, carbon, manganese, and iron, among other metals. While most of these metals rust, stainless steel is largely protected from rusting by chromium. WebAug 4, 2024 · Steel is made into “stainless” alloys with the addition of 4 percent to 30 percent chromium, and the typical stainless steel alloys contain about 10 percent chromium. In the alloys, chromium reacts with oxygen to form a tough, passive surface layer of chromium oxide that prevents iron in the alloy from oxidizing to form rust.
WebNov 25, 2024 · Stainless steel is an iron alloy composed primarily of iron and chromium. The chromium in the material reacts with oxygen on the surface to create an oxidized “passive layer”, which prevents corrosion and rust.
