Learn About Stainless Steels

Stainless steels are steels with a minimum of 10.5% chromium. They gain their resistance to corrosion from a thin, tenacious surface layer of chromium oxide. If the oxide layer is physically damaged there is rapid regeneration of the layer, thus preserving the corrosion resistance. However, a chemical environment that can disrupt this layer can initiate corrosion. consequently, stainless steel is highly resistant to atmospheric corrosion, but not immune to corrosion in all environments.

Stainless steels fall into several general classes: austenitic, ferritic, martensitic, duplex, and precipitation hardened. The distinction between each class is based primarily on the predominant phase present in the stainless steel as determined by the major alloying elements.
