According to the performance characteristics and uses of steel plates, it is divided into nitric acid-resistant stainless steel plates, sulfuric acid-resistant stainless steel plates, pitting-resistant stainless steel plates, stress corrosion-resistant stainless steel plates, and high-strength stainless steel plates. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, non-magnetic stainless steel plate, free-cutting stainless steel plate, superplastic stainless steel plate, etc. The commonly used classification method is to classify according to the structural characteristics of the steel plate, the chemical composition characteristics of the steel plate and the combination of the two.
Generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, etc. or divided into two categories: chromium stainless steel and nickel stainless steel. Wide range of uses Typical uses: pulp and paper equipment heat exchangers, mechanical equipment, dyeing equipment, film processing equipment, pipelines, exterior materials for buildings in coastal areas, etc.
Stainless steel has a similar resistance to general corrosion as the unstable Nichrome 304. Prolonged heating in the temperature range of chromium carbide degrees may affect Alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, which require strong resistance to sensitization of the material to prevent intergranular corrosion at lower temperatures.
