Никель улучшает металлическую основу сплава. Хром, марганец, никель, молибден, медь, ванадий, тантал, ниобий, бор повышают прочность стали. Ванадий и ниобий препятствуют образованию и развитию трещин при механических нагрузках.Nickel improves the metal base of the alloy. Chrome, manganese, nickel, molybdenum, copper, vanadium, tantalum, niobium, boron increase the strength of steel. Vanadium and niobium prevent the formation and development of cracks under mechanical stress.

Сталь может быть выплавлена в электропечах. Термическая обработка стали включает нагрев до температуры 1020-1100°С и закалку в воде.Steel can be smelted in electric furnaces. Heat treatment of steel includes heating to a temperature of 1020-1100 ° C and quenching in water.
