|Stainless Steel||Stainless steel is a family of corrosion resistant steels. They contain at least 10.5% chromium, with or without other elements. The Chromium in the alloy forms a self-healing protective clear oxide layer. This oxide layer gives stainless steels their corrosion resistance.||Good corrosion resistance, appearance, and mechanical properties|
|Austenitic Steels: Contains chromium and nickel. The typical chromium content is in the range of 16% to 26%; nickel content is commonly less than 35%.||Good mechanical and corrosion resisting properties, high hardness and yield strength as well as excellent ductility and are usually non-magnetic||Kitchen sinks, architectural applications such as roofing, cladding, gutters, doors and windows; Food processing equipment; Heat exchangers; Ovens; Chemical tanks|
|Ferritic Steels: Magnetic with a high chromium and low nickel content usually alloyed with other elements such as aluminum or titanium.||Good ductility, weld-ability, and formability; reasonable thermal conductivity, and corrosion resistance with a good bright surface appearance||Automotive trim, catalytic converters, radiator caps, fuel lines, cooking utensils, architectural and domestic appliance trim applications|
|Martensitic Steels: Typically contains 11.0% to 17.0% chromium, no nickel, and 0.10% to 0.65% carbon levels. The high carbon enables the material to be hardened by heating to a high temperature, followed by rapid cooling (quenching).||Good combination of corrosion resistance and excellent mechanical properties, produced by heat treatment, to develop maximum hardness, strength, and resistance to abrasion and erosion.||Cutlery, scissors, surgical instruments, wear plates, garbage disposal shredder lugs, industrial knives, vanes for steam turbines, fasteners, shafts, and springs|
