20KH20N14S2 — chromium-Nickel high-alloy heat-resistant steel austenite-ferritic class, used for the manufacture of such products as metal sheet, strip, foil. In its composition, 19−22% Cr, 12−15% Ni. As additives to the mixture used 2−3% silicon, up to 1.5% manganese, 0.3 percent copper, 0.2% of titanium and carbon, thousandths of a percent of phosphorus and sulfur.
Percentage composition of the brand 20KH20N14S2 (GOST 5632−72)
A thin sheet made according to the requirements of the following GOST: 5582−75, 19 904−74, 19 903−74, strip — GOST: 103−76, 4405−75. The forging process starts at a temperature of 1170 °C and ends at 850 °C. Accuracy production of sheet, strip, foil marked with the letters A and B: high and normal precision, respectively. If the edge of the finished product cutting, the product is marked with the letter «O», timber edge is denoted by a «BUT.» The products are characterized by such an indicator as the flatness, which can be particularly high (marked as PO), high (marked as DF), improved (labeled PU) and normal (marked — PN).
Cold-rolled sheet and strip can be negativnye (indicated by «H1»), prolongatorami (ПН1), annealed (soft M4V), after bright annealing or etching (group M2a, M3A, М4а). Hot rolled steel can also be: soft (М4г) heat treated, etched or after bright annealing (M2, М3б, М4б).

The use of high-alloy steels, including steel 20KH20N14S2, it is advantageous in metallurgy, woodworking, food processing, construction, interior design, Sheet, strip, foil are part of the high temperature furnace parts, boxes for the saturation of metal products with carbon (carburizing); in the manufacture of furnace conveyors used in food production. if any decoration. Sheet and strip used in construction. Thick sheet can serve as the basis for the design of columns, beams, thin sheet used for roofing. Also in the construction you can use the broadband sheet, tape, they do not require alignment of the edges and can be produced according to the specified standards. Corrugated sheet can be used for different coatings to prevent slipping, and a steel expanded sheet is an essential coating in areas where it is expected a large accumulation of dirt and dust. Foil 20KH20N14S2 used in the technology of fiber-optic cables for different applications.
