SS304 ASTM 2B Stainless Steel Strip 5mm Thickness 200mm Width Cold-Rolled Bright Color
Stainless steel is the name given to a group of corrosion resistant and high temperature steels. Their remarkable resistance to corrosion is due to a chromium-rich oxide film which forms on the surface. When ordinary carbon steel is exposed to rain water, for example, it corrodes forming a brown iron oxide, commonly called rust, on the surface. This is not protective and eventually the entire piece of steel will corrode and be converted to rust. But when enough chromium (more than about 10%) is added to ordinary steel, the oxide on the surface is transformed – it is very thin, virtually invisible and protective in a wide range of corrosive media. This is what we call stainless steel and there are several different types, and many different grades.
The manufacture of quality stainless steel, from heat to heat and year to year, demands precise control of raw material ingredients and melting practices. Exact quantities of presorted scrap and alloying elements are delivered to the mills’ melting furnaces so that the heats or lots will be within specified composition ranges. Those composition ranges typically include a group of chemical elements for each grade of stainless steel.The basic composition of stainless steel is iron (Fe) and chromium (Cr). This is the simplest form of stainless steel, with this family known as the ferritic stainless steels because their crystal structure is called ferrite. (This is also the structure of mild steel.) The ferritic stainless steels are magnetic like ordinary steel. A commonly used grade is Type 430 (S43000) which is used for automotive trim and inside dishwashers and clothes dryers. They are often the least expensive stainless steels but can be more difficult to form and weld.If you wish to make carbon steel strong and hard, such as for a drive shaft or wear plate, the mill might increase the carbon content, and then heat treat the steel by quenching and tempering it. The same can be done with stainless steel – if the carbon content of ferritic stainless steels is increased, it produces the family of martensitic stainless steels, used for items such as knives, razor blades and corrosion resistant bearings. Martensitic grades are strong and hard, but are brittle and difficult to form and weld. Type 420 (S42000) is a typical example. Like ferritic stainless steels, martensitic stainless steels are magneti.
