Technical feature
Stainless heat-resistant high-alloy chrome-nickel steel. Other name is Х25Н20С2 (ЭИ283). The basis of the alloy - iron: its share is about 46%. It is used in the production of furnace conveyors, parts of thermal furnaces, cementation boxes and similar parts working at t° up to 1100 °C in air or hydrocarbon atmosphere. Service life of more than 10,000 hours. Tendency to temper embrittlement.
