*Kuwanda kweManganese kunogona kuwedzerwa ne0.05% pakudzikira kwega kwega kwe 0.01% kwehuwandu hwekabhoni kusvika 1.35%.
**Kuwanda kweNiobium, zvichibva pakubvumirana, kunogona kuwedzerwa kusvika ku0.05% pakuongororwa kwekunyunguduka uye 0.06% pakuongororwa kwechigadzirwa chapera.
Zvinodiwa pakurapa kupisa:
1. Ita kuti tembiricha isvike pamusoro pe815°C.
2. Ita kuti tembiricha isvike pamusoro pe815°C, wobva waita kuti tembiricha iwedzere.
3. Kupisa kwakagadzirwa pakati pe845 ne945°C, kwozotonhodzwa muchoto pamusoro pe845°C (kune machubhu asina musono chete).
4. Yakagadziriswa uye yozogadziriswa sezvataurwa pamusoro apa.
5. Yakaomeswa yozonyoroveswa pamusoro pe815°C.
