Alloy 58НХВКТБЮ (ЭП877; ХН58ВКБТЮ)
Designation
Description
Alloy 58НХВКТБЮ used: for the manufacture of ingots, hot-rolled and forged bars intended for the production of highly loaded high-temperature elastic elements of Aviapribor and automatic systems of aircraft.
Note
High-temperature age-hardening Nickel-based alloy.
Standards
Chemical composition
Ni is the basis.
According to TU 14-1-3182-81, the chemical composition is given for the alloy grade 58NHVKTVBU-VI (EP877-VI). Boron, lanthanum and yttrium are introduced by calculation and chemical analysis is not determined. In the finished product, deviations in chemical composition are allowed: cobalt -0.50%, sulfur +0.0030%, copper + 0.030%. The alloy allows the presence of lead, antimony, tin, bismuth and arsenic not more than 1 point of the special analysis scale. The content of residual elements in the alloy in accordance with GOST 5632.
