According to OST 1 90126-85 the chemical composition is given for alloy VZhL14N-VI. Boron and cerium are introduced by calculation and chemical analysis are not determined. The alloy is allowed to deviate by carbon minus 0.010%, for aluminum plus 0.20%, for titanium plus 0.10%. In the alloy, the presence of non-deformable elements is allowed: cobalt and tungsten not more than 0.30% (each element), vanadium not more than 0.10%.
