General term for stainless steel sheet
We call the stainless steel plate, stainless steel plate is generally stainless steel plate and acid-resistant steel plate. Coming out at 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 gradually formed several categories in the process of development. According to the structure is divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardened stainless steel plate), ferritic stainless steel plate, and austenitic ferritic two-phase stainless steel plate and so on four categories? According to the main chemical composition of steel plate or some characteristic elements in steel plate to be classified 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 and so on. According to the performance characteristics and use of steel plate classification, it is divided 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, it is divided into low temperature stainless steel plate, no magnetic stainless steel plate, easy cutting stainless steel plate, super plastic stainless steel plate and so on. The commonly used classification method is according to the structure characteristics of steel plate and steel plate chemical composition characteristics 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. Typical uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film washing equipment, pipeline, coastal area building external materials, etc. Each enterprise on their own product demand, purchase stainless steel material model of stainless steel.
Stainless steel processing manufacturers believe that the mechanical properties of investment cast stainless steel are higher than cast iron, because of its high melting point, easy oxidation of molten steel, poor liquidity of molten steel, large shrinkage rate, volume shrinkage rate of 10-14%, line shrinkage rate of 1.8-2.5%. In order to prevent defects such as insufficient pouring, cold isolation, shrinkage cavity and porosity, crack and sand adhesion of steel castings, more complex technological measures should be taken than that of cast iron:
Stainless steel processing surface treatment process and construction process details, stainless steel processing surface treatment process what? We can common stainless steel surface treatment technology processes are: drawing, mirror, sandblasting, titanium plating, etching, anti-fingerprint, there are many students in the interior decoration of wonderful applications.
Stainless steel processing characteristics Stainless steel processing characteristics are: high cutting temperature, cutting is not easy to break, easy to combine, cutting force, serious hardening, tool wear. Stainless steel refers to alloy steel with chromium content greater than 12% or nickel content greater than 8%. This steel has China's certain corrosion resistance in atmospheric or corrosive environmental media, and can be used at a higher operating temperature (> 450℃). It has very high strength.
