General Characteristics
Grade 36NKhTU5M belongs to precision alloys with specified elastic properties. It is used for elastic sensing elements of sensors operated at t° up to 350 °C. The group of precision alloys stands out for their exclusive physical and chemical properties (magnetic, thermal, elastic, electrical), due to the balanced composition, thoroughness of manufacturing and processing, absence of unnecessary impurities. This group includes high-alloys based on iron, cobalt, copper, nickel and niobium.
