The steel sheet of alloy 20Х23Н18 (AISI 310s) is made of a complex alloy of austenitic class, resistant to soil and atmospheric moisture, aggressive industrial gases. According to GOST 5632−72, the main alloying element 20Х23Н18 is chromium in the amount of 22−25%. With increasing its share, corrosion resistance increases. 17% Cr makes steel resistant in aggressive oxidizing environments. 12−15% Ni in the composition impart the necessary ductility and increase the heat resistance and corrosion resistance. In addition, the 20Х23Н18 alloy is doped with 2% Mn, 1% Si, 0.2% C, thousandths of a percent phosphorus and sulfur.
The percentage composition of 20Х20Н14С2 (GOST 5632−72)
Thin sheet and thick plate semi-finished products 20Х23Н18 are rolled in cold-rolled or hot-rolled manner according to the following GOST: 7350−77, 19,903−74, 19,904−74. The surface can be rough, homogeneous matte or decorative (etched). A sheet on which traces of grinding are visible can serve as a blank for cold rolling.

Suspension brackets, bandages, clamps, details of fastening of boilers, combustion chambers, muffles for operation at t ° 1100 ° C. 20Х23Н18 sheet is used in the automotive, chemical industry. In the food industry, such sheets serve for the production of heat-resistant dishes, cutlery. These sheets meet the strictest sanitary and hygienic standards. Together with wood and stone, the steel sheet is used for interior decoration in high-tech style. The surface of the sheet can be ground, matte, mirror, matte mirror, decorative. Different textures give unusual external effects. In color versions of sheets colored by oxidation, the color does not change with time. Due to the resistance to atmospheric moisture, such a sheet is used in structures under the open sky. A sheet of Russian production is often used for window openings, handrails, shop windows, fireproof fire doors.
