The term "stainless steel" is more than just a stainless steel. It is a kind of stainless steel, which is more than one hundred kinds of stainless steel. The key to success is to find out what is right, and then determine the correct type. There are only six types of steel related to the application of building construction. They all contain 17 to 22% chromium, good steel also contains nickel. The addition of molybdenum can further improve atmospheric corrosion, especially the corrosion resistance to chloride containing atmosphere.Stainless steel is often divided into: martensitic steel, ferritic steel, austenitic steel, austenitic ferrite (duplex) stainless steel and precipitation hardening stainless steel. In addition, according to the composition is divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel.
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Due to the differences in the chemical composition of the different corrosion resistance, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally non rust.
This depends on the stress, the melting point of steel 1500+ degrees C, no external force, until the melt will not be deformed, 350 degrees of steel for the lower temperature, that is, tempering temperature. Not deformed.
