Strip made of this alloy is non-magnetic. It possesses heat resistance, corrosive resistance. It is meant to be used in aggressive environment in a temperature range of 100−850°C. Its oxidation rate constitutes 0,03 mm/h in free atmosphere at a t° of 800 °C. Such a strip has significant short term limit of strength (500 MPa). Its flow limit is 180 MPa; imperceptible elongation at break is 30%. Strip is fairly workable and can be mechanically treated. It is a durable, reliable, aesthetic steel. Due to this, it is much-in-demand in spheres of national economy. This malleable strip possesses resistance in oxidising atmosphere, in environment of ammonia, nitrogen. Its surface does not oxidize at durable exploitation or at a high temperature. Its main demerit is that a wire does not have a stability in atmosphere of sulphur and sulphur compounds.
Alloy is smelted in open electric furnaces. It provides a minimal content of unnecessary residual elements. Percentage composition is compliant with GOST 5632−72. Flat products are released in the form of hot-rolled and cold-rolled sheets or strips. There should be done thermohardening of strip (t° = about 1100°C) and further cooling in water or in air for strength increasing. Age-hardening performs at a temperature of 700−750°C during 5−16 hours (depending on type of mill-products). Such heat treatment conduces to normalization of inherent stress in alloy and to increasing of strength characteristics of details.
