Steel sheet, strip, foil stamp 20H25N20S2 made from stainless steel complex-temperature-resistant and heat-resistant alloy. The composition in accordance with GOST 5632−72, 24−27% Cr, 18−21% Ni, 2−3% Si. The alloy is doped with vanadium, tungsten, titanium and carbon — 0.2% manganese, copper and molybdenum — 0.3%, in thousandths of phosphorus and sulfur. Balance is iron. Since chromium and nickel are major alloying elements of chromium-nickel steel referred to.
The percentage composition in accordance with GOST 5632−72
Sheet, strip and foil can be produced by hot and cold rolling. Thickness 1.5 — 3.9 mm is achieved by hot rolling, less than 0.7 mm, and — cold-way. hot working temperature is 1170 ° C at the beginning and 850 ° C at the end of the process. Cooling is performed in air. Sheet and strip can be matte, polished, honed. Perhaps the production of expanded metal technique and others. Expanded articles are cut and pulled out of the hot-rolled steel with a thickness up to 6 mm, or cold rolled steel to a thickness of 2 mm; used stair structures, fences, balconies and so on. n. The quality of products can be ordinary and structural. A method of finishing edge of the sheet along the edges defined by its edges. Rolling can be performed with high accuracy and normal. Rolled steel is produced with a thickness of 4 to 16 cm.
Heat resistance during, t ° to 1100 ° C, corrosion resistance, including in an oxidative environment, aesthetic appeal. Properties such as high strength, wear resistance, and allow the use of a sheet as a blank tape for manufacturing critical components used at high loads and temperatures. Due to nickel and chromium protective film on the surface of the parts quickly restores itself after a minor injury. The disadvantage is considered to be a tendency to temper brittleness.

Sheet and strip are used for high-temperature furnaces parts and various types of fasteners, stainless steel complex structures. They are used in power engineering, chemical and heavy machinery, petrochemical industry. This material has a very attractive appearance, so it is popular in the construction industry. With it, you can make any finishing facades and premises, decorative cabinet and furniture. A variety of methods for surface treatment of high-alloy stainless sheet provide an opportunity to decorate any space, for example, the elevator, the steps to improve the reliability, make them less slippery due to the grooved surface. Sheet and strip are used for the production of heat-resistant cookware. foil is used in the chemical industry.
