Heat-resistant alloy of the brand HN55VMTKYU (EI929, EI929-VD, HN55VMTKYU-VD) is used in the production of turbine blades, components of gas turbine engines. It is designed for a limited period of operation at temperatures up to 950 ° C. Home intense scaling takes place at a temperature of 1050 ° C. alloy hardness HN55VMTKYU at the end of quenching and aging: HB 10−1 = 285 — 341 MPa. Rod is made according to GOST 23 705−79.

The main requirements to the material for turbine blades are caused by the latest developments of the engines design, increased flexibility, heat resistance, resistance to low-cycle fatigue and heat, as well as resistance to gaseous media. In modern engines material for turbine components must have a high resistance to fracture at low-cycle fatigue and heat, which is today the main cause of the destruction. The danger may be aggravated by the destruction of surface reactions that are associated with the softening of grain boundaries, corrosion gas.
