Pour: ① . Verminder die boonste limiet met 0 . 01% koolstof, wat 0 . 04% addisionele mangaan toelaat. Vir zg 200 ~ 400 mangaan tot 1,00%is die oorblywende vier graad mangaan hoog tot 1,20%.
② . Die totale hoeveelheid oorblywende elemente mag nie 1 . 00%. oorskry as die koper nie nodig is nie, die oorblywende elemente moontlik nie geanaliseer word nie.
③ . Wanneer suuroond gebruik word om gietstukke te produseer, moet die inhoud van S en P deur beide partye ooreengekom word .
