* Ibirimo Mangane birashobora kwiyongera kuri 0.05% kuri buri 0,01% kugabanuka kwa karubone kugeza kuri 1.35%.
** Ibikubiyemo Niobium, bishingiye ku masezerano, birashobora kwiyongera kugeza kuri 0.05% yo gusesengura na 0.06% kubisesengura ibicuruzwa byarangiye.
IBISABWA GUKURIKIRA:
1. Bisanzwe hejuru ya 815 ° C.
2. Bisanzwe hejuru ya 815 ° C, noneho uburakari.
3. Bishyushye byakozwe hagati ya 845 na 945 ° C, hanyuma bikonje mu itanura hejuru ya 845 ° C (kubibyimba bitagira ingano).
4. Yakozwe hanyuma akangirika nkuko byavuzwe haruguru ingingo ya 3.
5. Gukomera hanyuma ukandagira hejuru ya 815 ° C.
