Kuthilira:①. Chepeskani mphaka ya pachanya na 0.01% carbon, kuzomerezga 0.04% manganese yakusazgikira. Kwa ZG 200 ~ 400 manganese mpaka 1.00%, manganese ya vyaka vinayi ivyo vyakhalako kufika pa 1.20%.
②. Mtengo wose wa vinthu vyakukhalira uzamujumpha yayi 1.00%. Usange uyo wakugura wakukhumba yayi, vinthu vyakukhalapo vingasangika yayi.
③. Para ng’anjo ya asidi yikugwiriskirika nchito kuti yipangiske vigaŵa, ivyo vili mu S na P vikwenera kuzomerezgeka na vipani vyose viŵiri.
