Stainless steel plate is generally the floorboard of stainless steel plate and acid resistant steel plate. Stainless steel plate refers to the atmospheric, steam and water weak medium corrosion of steel plate, and acid resistant steel plate refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel plate. Stainless steel plate came out at the beginning of this century, and the development of stainless steel plate laid an important material and technical foundation for the development of modern industry and the progress of science and technology. There are many kinds of stainless steel plate and various properties, which gradually form several categories in the process of development. According to the organizational structure is divided into austenitic stainless steel plate, stainless steel plate (including Martensite Precipitation Hardening Stainless steel plate), ferritic stainless steel plate, and the austenite and ferrite dual phase stainless steel plate and other four categories? According to some characteristic elements of main chemical components of steel plate or in the classification, divided into chromium stainless steel plate chromium nickel stainless steel plate, nickel chromium molybdenum stainless steel plate and stainless steel plate, low carbon and high molybdenum stainless steel plate, stainless steel plate, high purity. According to the performance characteristics and use of steel plate classification, divided into nitric acid stainless steel plate, sulfuric acid resistant stainless steel plate, pitting corrosion resistant stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate. According to the functional characteristics of the steel plate classification, divided into low temperature stainless steel plate, non-magnetic stainless steel plate, easy cutting stainless steel plate, superplastic stainless steel plate. The commonly used classification methods are classified according to the structural characteristics of steel plate, chemical composition characteristics of steel plate and the combination of the two methods. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation hardening type stainless steel plate, or divided into chromium stainless steel plate and nickel stainless steel plate two categories. Widely used, typical uses: pulp and paper equipment, heat exchangers, machinery and equipment, dyeing equipment, film washing equipment, pipes, coastal areas outside the building materials and so on.
There are two kinds of hot rolling and cold rolling, including thin cold plate with thickness of 0.5.10-885 mm 72938 and medium thickness plate with 4.5-100 mm.
Can withstand oxalic acid, sulfuric acid iron sulfate, nitrate, nitrate acid and hydrofluoric acid, sulfuric acid copper sulfate, phosphoric acid, formic acid and acetic acid and various acid corrosion, widely used in chemical, food, medicine, papermaking, petroleum, atomic energy industry, as well as construction, kitchen utensils, cutlery, household appliances, vehicles of all kinds of parts.
In order to ensure that all kinds of stainless steel plate mechanical yield strength, tensile strength, elongation and hardness to meet the requirements, the plate must be after annealing, solid solution treatment, aging treatment and heat treatment of 5.10 88.57.29.38 special symbols before delivery.
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure.
There are two kinds of hot rolling and cold rolling according to the method of production. They are divided into 5 types according to their microstructure characteristics: austenite type, austenite ferrite type, ferrite type, martensite type and precipitation hardening type.
Stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, corrosion of acid, alkaline gas, solution and other media. It is a kind of alloy steel which is not easy to rust, but not absolutely rusty.
