Chromium-Nickel steel 20H23N18 (ЭИ417) belongs to the category of heat-resistant alloys of austenitic class. High quality steel allow to use it in an oxidizing atmosphere at t° to 1050 °C. Chromium and Nickel, the total percentage of which in the alloy may reach 45%, protect the surface of structures, from wet corrosion and corrosion cracking in alkaline and chloride environments, gives resistance to intergranular corrosion. Supplements silicon, manganese, titanium additionally improve manufacturability and performance.
Percentage composition according to GOST 5632−72.
Steel is smelted in open electric furnaces. Rashkovka semi-finished products is in the range of 1180 °C to 900 °C and tempering at t° 1050°-1150°C With cooling in water or air.
