WebAug 14, 2024 · Stainless steel is known for its corrosion resistance in many environments in which carbon and low alloy tool steels would corrode. The corrosion resistance is a result of a very thin (about 5 nanometers) oxide layer on the steel's surface. This oxide layer is referred to as a passive layer since it renders the surface electrochemically passive ... WebReference is often made to stainless steel in the singular sense as if it were one material. Actually there are well over 100 stainless steel alloys.
