Composition and properties

Sheet, strip and foil of 15X25T (EI439) ferritic class steel are compound alloyed stainless steel products. Their composition according to GOST 5632- - - - - - 72 chromium 24-27%, up to 1% silicon, 0.8% manganese, 0.5-0.9% titanium, 0.15 carbon, thousands of percent phosphorus and sulfur. Products are high-tech, sheet and strip are easily hot deformed at t° 1000-700°C and cold deformed at t° 150 - 200°C.

Application

Sheet, strip and foil of steel 15X25T are reliable in oxidizing environments, in the production of salt or caustic soda. They are heat-resistant, ductile, resistant to static loads, used in structures not subject to the action of vibration and shock, operated at t ° C from -20 ° C to 1100 ° C. Sheets, tapes are used for the production of furnace fittings, welded pipes operating in an aggressive environment, are used in the oil, chemical industry, for water and gas drainage. Sheet, strip and foil are successfully used in metallurgical production, mechanical engineering, household - for the production of heat-resistant utensils.
