Description Steelun of ЭИ763 Alloy structural steel:

ЭИ763 steel is used: for the manufacture of critical shtampovannyh structures; for heavy welded assemblies and structures, not subjected to the annealing or normalizing after welding due to large dimensions or design features, as well as welded and nesvorny parts operating at temperatures up to 500 °C.

Note

Complex alloyed high-quality steel with low carbon content. Steel 19KH2NVFA (ЭИ763) strengthen by heat treatment (quenching in oil with subsequent tempering or normalizing with tempering).
