This heat-resistant alloy on the iron (iron-nickel) base is used in the manufacture of flat springs, rotors, disks, fasteners, produced by cold upsetting, as well asAs well as turbine blades and various turbine parts which are operated at temperatures up to + 650°C according to GOST 5632-72 "Heat-resistant, corrosion-resistant, heat-resistant and high-alloy steels. Grades", as well as technical specifications 14-11-245-88 "T. У. Shaped steel sections of high precision. The material in modern engines for turbine blades has to have high fracture resistance under thermal, low-cycle fatigue, which is the main type of fracture today. The risk of fracture can be exacerbated by surface reactions due to softening of grain boundaries and gas corrosion. The main requirements to the material for the turbine blades production are caused by the latest developments of the engine designs, continuous increase of plasticity, low cycle resistance, thermal fatigue, heat resistance as well as the resistance to the influence of gas media.
