The corrosion resistance of stainless steel arises from a passive,chromium-rich,oxide film that forms naturally on the surface of the steel.The mechanisms of corrosion include crevice corrosion,pitting corrosion,intercystalline (or intergranular) corrosion (ICC),stress corrosion cracking (SCC) and galvanic (bi-metallic) corrosion BSSA Understanding Stainless Steel Centenary Edition Understanding Stainless Steel Centenary Edition is packed with indispensable information on stainless alloys.What it is,how it is manufactured,where and why it is used,what types and grades are available,and much more both for beginners in the field and those who wish to

MartensiticFerriticAusteniticIn general,martensitic stainless steels are considered moderate when it comes to corrosion resistance.Like low alloy or carbon steels,martensitic stainless steels are similar in structure to ferritic,but can be hardened or strengthened by heat treatmentwhich can also make them more brittle.This is due to the addition of carbon.The main alloying element of this family is chromium.The oil industry is a heavy user of martensitic stainless steel,as is the medical fieldprimarily for surgical equipment.Among the mostSee more on ryersonOvercoming Saltwater Corrosion with Stainless Steel UlbrichAustenitic stainless steels,such as 316 or 316L stainless is a metal with very high corrosion resistance.It has an increased molybdenum and manganese content,which gives the metal corrosion protection and higher strength.This makes 316L stainless steel an option for many applications in corrosive environments.How heat treating and annealing stainless steel impacts Annealing these stainless steels softens them,adds ductility and imparts improved corrosion resistance.300-series stainless steels are the most popular examples of this type.The most popular of the 300-series steels304 stainless steel is revered for its very good corrosion resistance and is commonly used in cookware.
