Sheet, round, wire ХН50ВМТЮБК - ЭП969
High-temperature multicomponent alloy on the iron-based ХН50ВМТЮБК-ID (ЭП648; ХН50ВМТЮБ; ХН50ВМТЮБ-VI; ЭП648-VI) relevant in the production of sheet blanks for the production of loaded parts with a limited service life (fittings, flanges), working at t° to +950°C. Of the steel parts are made of aircraft engines (turbine blades, disks).
In the heat-treated σВ=951 MPa, HB 269, b Kυ, Kυ TV, CPF=0.3 and St=0.15 steel must be cut at lower rpm. Welded by manual arc method with the help of electrodes KTI-762. To reinforce the seam the required final heat treatment is recommended to relieve residual stresses.
