Designation

Description

Alloy In 1963 used: for the manufacture of highly stressed parts of an internal set of glider (such as frames, fittings, beams, etc.) in products promising aerospace technology.

Note

New high strength forging alloy. Due to the alloying with silver and scandium managed to simultaneously increase the strength characteristics (σ_in≥560−580 MPa; σ_0,2≥480−520 MPa; δ>8%) — 10−20%, the viscosity of the fracture is 15−25% and the fatigue resistance of 1.8 — 2.3 times compared to the production of domestic and foreign alloys. The alloy also has improved characteristics of weldability compared with similar alloys without silver (σ_{V. SV} = 0,7 σ_in).
