Stainless steel plate is generally the floorboard including stainless steel plate and acid-resistant steel plate. Stainless steel plate is a kind of plate to resist weak media like air, steam and water corrosion; while acid resistant steel plate is a type of plate to resist chemical etching mediator referred to acid, alkali, salt etc. corrosion. Stainless steel plate has been a long history since it appeared this century.The stainless steel plate establishes important material and technology bases for the development of modern industry and science and technology progress.
 
Stainless steel plate has many different varieties and performance. And it has formed a few broad categories in the developing gradually. According to structure organization, it is divided into martensite stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, austenitic stainless steel plate and austenitic with ferritic stainless steel plate; According to main chemical composition or some characteristic elements of steel plate, it also can be divided into chromium stainless steel plate, chromium nickel stainless steel plate, low carbon stainless steel plate, high molybdenum stainless steel plate and high purity stainless steel plate; According to features and applications, it also can be divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting corrosion resistant stainless steel plate and high strength stainless steel plate etc. According to functional characteristic, it also can be low temperature stainless steel plate, non-magnetic stainless steel plate, free cutting stainless steel plate and super plastic stainless steel plate etc. While the common classification methods are the structural features and chemical compositions. According to processing technology, it is divided into hot rolling and cold rolling including thin cold plate of thickness 0.***4 mm and middle plate of thickness ****5 mm. According to the characteristics of steel grade, it is divided into five types including austenite, ferrite-austenite, ferrite, martensite and precipitation hardening.
In order to guarantee all kinds of stainless steel to meet requirements in yield strength, tensile strength, elongation, hardness and other mechanical properties, the steel plate must be annealing, solid solution, and aging etc.
