Stainless steel coils have the following advantages: 1. Strong corrosion resistance: The surface of stainless steel coils has a dense chromium oxide film, which can prevent corrosive media such as oxygen and moisture from coming into contact with the internal metal substrate, allowing it to remain stable and not easily rust in corrosive environments such as humidity and acidity. For example, in o

1. Different production processes Stainless steel hot rolling is rolled above the recrystallization temperature of the metal material, and stainless steel cold rolling is rolled below the recrystallization temperature of the metal material, and each metal material has its own recrystallization temperature. crystallization temperature.
2022-07-25Classify and organize according to new energy, traditional electricity, oil and gas petrochemicals, hydrogen energy, and nuclear power, and distinguish three types of uses: ultra-thin precision steel strips, structural bundling steel strips, and heat-resistant conveyor steel strips:
Stainless steel has high deformation resistance, is prone to work hardening, is easily oxidized at high temperatures, and is prone to cracking at the edges. It is divided into two parts: hot-rolled billet rolling and cold-rolled precision rolling. The raw materials, temperature, process parameters, equipment, lubrication, plate shape tension, surface protection, and later microstructure and proper
Hot rolled stainless steel coil is a thick material coil produced by high-temperature rolling, with a thickness range of 1.5-16mm and a surface with oxide black skin. It is thick in size, high in strength, and does not require appearance. It is mainly used in structural pressure bearing, chemical equipment, and heavy machinery scenarios.
1、 Core material foundation: 304/316L itself is austenitic non-magnetic stainless steel 304 and 316L belong to austenitic stainless steel. In the factory solution annealed state, all internal crystals are austenitic structure, and the austenitic crystal structure does not have ferromagnetism. The new soft steel strip is almost non-magnetic, and the magnet does not adsorb.
1、 Open coil basic processing (the first process of coil material) 1. Kaiping/Splitting Kaiping: Stainless steel coils are uncoiled, leveled, and cut into flat plates (stainless steel plates) for cutting, bending, and laser cutting. Slitting: Large rolls are cut into narrow strips of steel for welding pipes, steel strips, precision stamping, strapping, and decorative edge strips.
