Stainless steel plate has a smooth surface, high plasticity, toughness, and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions, and other media. There are many types of stainless steel plates with different properties. It has gradually formed several categories in the development process. According to the structure, it is divided into four categories: austenitic stainless steel, martensitic stainless steel (including precipitation hardening stainless steel), ferritic stainless steel, and austenitic plus ferrite duplex stainless steel. According to the main chemical composition in the steel plate or some characteristic elements in the steel plate, it is divided into chromium stainless steel plate, chromium-nickel stainless steel plate, chromium-nickel-molybdenum stainless steel plate, low-carbon stainless steel plate, high-molybdenum stainless steel plate, high-purity stainless steel plate, etc. According to the performance characteristics and uses of the steel plate, 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, etc. 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, 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.
