Creep-resistant and heat-resistant H23N18 steel can be a chromium-nickel austenitic grade with higher nickel content compared to H23N13, high strength, ductility, resistance to high temperatures up to 1050 ° C in air and oxidizing atmosphere. Steel is used for mechanically loaded parts operating at high temperatures. Not every working environment is right for H23N18. Steel associated with reducing gases and containing higher concentrations of sulphur compounds withstands temperatures up to 900 ° C. It can exercise up to 1000°C with small impurities. parts of the furnace, fittings, hooks, stands, carriages, responsible screws, furnace casings, etc. using for.
