Stainless steel plate is generally divided into stainless steel plate and acid resistant steel plate. In the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technical foundation. There are many kinds of stainless steel plate, different performance, it has gradually formed several major categories in the process of development.According to the structure is divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, as well as austenitic ferritic biphase stainless steel plate four categories?According to the main chemical composition of steel plate or some characteristic elements in steel plate, it is divided into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate. Steel plate is classified into nitric acid resistant 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 is divided into low temperature stainless steel plate, no magnetic stainless steel plate, easy to cut stainless steel plate, super plastic stainless steel plate. At present, the commonly used classification method is to combine the two methods according to the structural characteristics of steel plates and the characteristics of the chemical composition of steel plates. 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. Typical uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film washing equipment, pipeline, coastal area building external materials, etc.Corrosion resistanceThe stainless steel plate has similar resistance to general corrosion as the unstable nichcr 304. Prolonged heating of chromium carbide temperature ranges may affect alloys 321 and 347 in harsh corrosive media. Primarily used in high-temperature applications, the material is required to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.High temperature oxidation resistance.Stainless steel plate has high temperature oxidation resistance, but the oxidation rate will be affected by exposure environment and product form and other inherent factors.Physical propertyThe total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the heat dissipation coefficient and corrosion of film are related to the metal surface condition. Stainless steel keeps the surface clean, so it transfers heat better than other metals with higher thermal conductivity. Eight, stainless steel plate technical standard stainless steel plate corrosion resistance, bending processing performance and toughness of welding parts, as well as welding parts of the stamping processing performance of excellent high strength stainless steel plate and its manufacturing method. Specifically, C content: less than 0.02%, N content: less than 0.02%, Cr content: more than 11%, less than 17%, Si, Mn, P, S, Al, Ni content is appropriate, And meet 12≤Cr Mo 1.5Si≤17 1≤Ni 30(C N) 0.5(Mn Cu)≤4,cr 0.5(Ni Cu) 3.3Mo≥16.0,0.006≤C N≤0.030 stainless steel plate heating to 850 ~ 1250℃, Then heat treatment was carried out at a cooling rate of more than 1℃/ S. This can become a high strength stainless steel plate containing 12% volume fraction with martensitic structure, high strength above 730MPa, good corrosion resistance and bending performance, welding heat affected zone toughness is excellent. Using Mo, B, etc., the stamping performance of welded parts can be significantly improved.Oxygen and gas flames cannot cut stainless steel plates because stainless steel is not easy to oxidize.
