SS Roll

With the development of SS roll, the corrosion resistance, appearance, processability and strength of SS roll are far superior to other materials.In addition, many surface treatment methods can obtain bright colors and shapes, which greatly improves its service life.Has contributed to the development of SS roll.SS roll has corrosion resistance, heat resistance, low temperature strength, excellent mechanical properties.Solid solution treatment does not harden, almost no magnetic.Specification range: 0.03-2.0mm thick x 5.0-1219mm wide x coilHardness: Vivtorinox hardness (HV) 160-600 degrees.Hardness: cold rolling ANN (DDQ), 1/4 H, 1/2 H, 3/4h, H, EH, SHSurface: 2B, NO.1, BA (6k), 8K, 9K, satin, hair, etcStandard: GB, ASTM, JIS, etc.

The heat treatment of SS roll is used to change its physical and mechanical properties without changing its shape.This is an essential process in the manufacture of SS rol, which can improve the ideal performance of SS rol and further process.Different SS rol heat treatment processes involve heating and cooling, such as steel heat treatment for a variety of commercial applications.The common purpose of heat treatment is to enhance strength, increase hardness, improve toughness, improve processability, improve formability, improve ductility and improve elasticity.The effect of the cooling phase varies with the stainless steel plate and process, and it hardens with the rapid cooling of the steel, while the rapid cooling phase of the solid solution annealing softens.

SS roll has several types according to its microstructure.Austenitic stainless steels contain at least 6% nickel and austenitic (carbonaceous iron with a face-centered cubic structure) and have excellent corrosion resistance and high ductility (the ability of materials to bend without breaking).Ferrite SS roll (ferrite with body centered cubic structure) has better stress corrosion resistance than austenitic stainless steel, but is difficult to weld.Martensitic stainless steel contains iron with a needle-like structure.Two-phase SS rolls, which usually contain an equal number of ferrite and austenite, offer better resistance to pitting and crevice corrosion in most environments.They also have excellent resistance to chloride stress corrosion cracking and are twice as strong as normal austenite.As a result, dual-phase SS roll is widely used in refineries, gas processing plants, pulp and paper mills, and seawater piping installations in the chemical industry.

SS roll is a widely used ferroalloy (a substance consisting of two or more chemical elements).As the chromium content is usually 12% to 20% of the alloy, it has excellent anti-stain and anti-rust properties.In addition to the many proprietary alloys produced by different stainless steel manufacturers, there are more than 57 recognized standard alloys, the ss roll.These various types of steel used in numerous applications and industries: almost bulk materials handling equipment, building walls and roof, auto parts (exhaust, decoration/decoration, engine, chassis, fasteners, fuel pipeline), chemical processing plant (scrubber and heat exchanger), pulp and paper, petroleum refining, water supply pipeline, consumer goods, shipping and shipbuilding, pollution control, sporting goods (sled) and transportation (tram).
