Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate. Introduced at the beginning of this century, the development of stainless steel plate has laid an important material and technical foundation for the development of modern industry and scientific and technological progress. 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 ferritic duplex stainless steel. The main chemical composition or some characteristic elements in the steel plate are classified 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 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. Also there are other types of stainless steel plates, such as 304 Stainless Steel Sheet, 316 Stainless Steel Plate, 301 Stainless Steel Sheet, etc.
Coils mainly refers to hot-rolled round steel with a diameter of 5-9mm and rebar with a diameter of less than 10mm. Most of them are supplied in coils by reeling machines, also known as wire rods or coils. Wire rods are mainly used as raw materials for reinforcing and welding structural parts of reinforced concrete or for reprocessing (such as wire drawing, drawing, etc.). According to the steel distribution catalogue, stainless steel coil includes ordinary low carbon steel rolled wire rod, electric welding wire rod, wire rod for blasting wire, quenched and tempered threaded wire rod, and high-quality wire rod. Suitable for petroleum, chemical, construction, medicine, food, machinery and other industries, and can meet the requirements of metal hoses, watch straps, pens, kitchens, tableware, auto parts, camera parts, precision electronics, mobile phones, household appliances and other materials requirements.
