50% / 80% Min 10 ~ 60mm Ferro Vanadium

Ahanini ikoreshwa mugushongesha ibyuma.Hafi ya 90% byisi yose ikoreshwa na vanadium ikoreshwa mubyuma.Vanadium mubyuma bisanzwe bisanzwe bivangwa cyane cyane bikoreshwa mugutunganya ingano, kongera imbaraga zicyuma no kugabanya ingaruka zogusaza.Mubyuma byubatswe byubaka, binonosora ingano kandi byongera imbaraga nubukomezi bwibyuma.Irashobora gukoreshwa mubyuma byimpeshyi hamwe na chromium cyangwa manganese kugirango wongere imipaka ya elastike yicyuma no kuzamura ubwiza bwayo.Itunganya cyane cyane imiterere nintete zicyuma cyibikoresho, ikongera ubushyuhe bwayo, ikongera imbaraga zayo ya kabiri ikomera, igahindura imyambarire kandi ikongerera igihe cyumurimo wibyuma.Vanadium kandi igira uruhare runini mubyuma birwanya ubushyuhe hamwe nicyuma cya hydrogène.Kwiyongera kwa vanadium mubyuma biteza imbere isaro rya pearlite bitewe no gukora karbide, ituma sima itajegajega, imiterere yibice bya grafite neza kandi bigahuza, gutunganya ingano za matrix, bityo bikazamura ubukana, imbaraga zikaze kandi kwambara birwanya gukina.
