Description

Steel 015Х18М2Б usedin chemical and petrochemical industry, for the manufacture of heat exchange equipment of power plants, operating in conditions of exposure to water-steam medium of high parameters; pipe systems separators-superheaters, steam generators, boilers, condensers, heating sections of the evaporators, and tube plates and housings with a wall thickness of not more than 10 mm). Maximum operating temperature under specified conditions +350 °C. Steel is recommended for use in the chemical, petrochemical, food, pulp and paper industry, as well as in conditions where is required high resistance to chloride cracking. Steel can be used as a heat-resistant material for low-loaded parts operating at temperatures up to +900 °C.
