Steel strip, sheet, foil of grade X15CrNiSi20−12 are made on the basis of chrome-nickel high-alloyed alloy, in which composition are presented nickel (-19−22%) and chrome (12−15%). As a means of masteralloys, there can be added manganese (up to 1.5%), copper (0.3%), silicon (2−3%), carbon (0.2%), titanium (0.2%), sulfur and phosphorus (parts per thousand). Jumping up temperature of semi-fabricates constitutes 1170 °C at the beginning and 850 °C at the end. Quenching is performed in air at a temperature of 1050−1150°C.

Manufacture of steel stainless sheets complies with GOST 24 982−81, which qualifies a making of hot-rolled and cold-rolled mill-products made out of smelted by open method heat-resistant alloys on iron-nickel basis. Steel stainless sheet is welded by a welding of any type.
Classification
X15CrNiSi20−12 sheet, strip, foil are classified by edge state, evenness and rolling accuracy level. Evenness categories: special, improved, standard and high. Accuracy: high and standard level. Edge: sheared or milled.
Application
It is used in welding equipment for mechanical engineering, energetics, medicine, and chemical industry. Such equipment is particularly requested in those industries where are needed the materials that possess high resistance to thermal stresses: in constructions of motors, turbines, combustion wells, different furnaces, heating installations etc. Carburizing pots in metallurgy are intended for carbon saturation by diffusion method. At that, low-carbon steel assumes high hardness and wear resistance. Usually, alloyed steels and alloys with carbon content of not more than 0.2% can be exposed to carbonisation. During carbonisation, there is reached a temperature of 850−900 °C. The following goods can be manufactured out of X15CrNiSi20−12 sheet: constructions, parts for space and rocket defence. A high content of nickel and chrome in composition allows the products to withstand a high temperature (>1000°C) and not to lose a high resistance to aggressive and acid environment.
