Mimina: ①. Punguza kikomo cha juu na kaboni 0.01%, kuruhusu manganese 0.04%. Kwa zg 200 ~ 400 manganese hadi 1.00%, manganese ya daraja nne iliyobaki hadi 1.20%.
②. Jumla ya vitu vya mabaki haizidi 1.00%. Ikiwa mnunuzi hauitaji, vitu vya mabaki vinaweza kuchambuliwa.
③. Wakati tanuru ya asidi inatumiwa kutengeneza castings, yaliyomo S na P yatakubaliwa na pande zote.
