The stainless steel plate is generally the general term of the stainless steel plate and acid-resistant steel. The stainless steel plate is weak medium corrosion resistance to atmospheric, steam and water steel, acid-resistant steel refers to acid, alkali, salt and other chemical etching medium corrosion of steel. Stainless steel plate come out since the beginning of this century, and now more than 90 years of history. The invention of the stainless steel plate is the world's significant achievements in the history of metallurgy, laid an important material and technical basis of the development of modern industrial development and technological advancement of the stainless steel plate. Stainless steel plate steel plate many kinds of different properties in the development process, it gradually formed a few categories. The organizational structure is divided into the Markov stainless steel (including precipitation hardening stainless steel), ferritic stainless steel, austenitic stainless steel and austenite and ferrite duplex stainless steel and other four categories? Steel chemical composition, or some of the characteristics of the steel sheet element to be classified into the chromium stainless steel plate, chrome-nickel stainless steel plate, chromium-nickel-molybdenum stainless steel plate, as well as low carbon stainless steel plate, high molybdenum stainless steel plate, high-purity stainless steel plate, etc.. Steel performance characteristics and use classification, divided into nitric acid-resistant stainless steel, resistant sulfur suan stainless steel plate, resistance to pitting corrosion stainless steel, stress corrosion-resistant stainless steel, high-strength stainless steel. The steel features classified into low-temperature stainless steel, non-magnetic stainless steel plate, stainless steel plate cutting, superplastic stainless steel. Commonly used classification method is at steel structure characteristics and the characteristics of the chemical composition of the steel and a combination of both classification. Usually divided into a martensitic stainless steel, ferritic stainless steel plate, austenite stainless steel, duplex stainless steel and precipitation hardening type stainless steel plate, etc.? Or divided into two broad categories of chromium stainless steel, and nickel, stainless steel plate. Very versatile? Mechanical equipment? Typical uses: pulp and paper equipment heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal areas of the building external timber and so on.
