1. Te waro (c) : I te mea ko te ihirangi waro i te kowiri ka piki ake, ko te waahi whakaputa me te kaha o te kaha o te kaha, engari he ngoikore te kaha o te uaua. Ka neke atu te ihirangi waro ki te 0.23%, ko te mahi a te kowiri o te kowiri. Na reira, ko te ihirangi waro o te kowhatu kowhatu iti te papatipu e whakamahia ana mo te mea kaore i neke atu i te 0.20%. Ko te ihirangi waro teitei ka taea hoki te whakaiti i te aukati i te hau o te kowiri, me te kowiri waro i roto i nga papa tuwhera ki te aukati; I tua atu, ka taea e te waro te whakanui ake i te tipu makariri me te kaha o te kowiri o te maitai.

2. Silicon (SI) : Kua tapirihia a Silicon hei whakaheke i te kaihoko me te Deoxidizer i te wa ko te kowiri, na kua mate te kowhatu 0.15-0.30 %% Mena ka nui ake te ihirangi silicon i te rino 0.50-0.60%, ka kiia a Silicon he waahanga taapiri. Ka taea e Silicon te whakapai ake i te rohe riki, te tohu me te kaha o te kowiri, na reira e whakamahia nuitia ana hei kowiri witi. Ko te taapiri i te 1.0-1.2% Silicon ki te tihorea me te kowiri hanganga tipu ka nui ake te kaha o te 15-20%. Ko Silicon i honoa ki a Mollybdenum, ko te puku, te chromium, me te kaha o te whakapai ake i te kaha o te whakapai ake i te aukati i te koriri. Ko te rino miihini iti kei roto i te 1-4% he tino nui o te silicon me te whakamahi i te umanga hiko ki te hanga i nga pepa maitai silicon. Ko te pikinga o te ihirangi silicon ka whakaiti i te mahi a te kowiri.

3. Manganese (MN) : I roto i te mahi kowiri tira, ko Manganese he Deoxidizer pai me te Desulfurizer. Ko te tikanga, ko te kowiri he 0.30-0.50% manganese. I te neke atu i te 0.70% o te kowiri tira ka tapiritia, ka kiia ko "Manganese maitai". Whakaritea ki te rino noa, kaore i te rahi noa te uaua, engari he kaha ake hoki te kaha me te uaua. Ka whakapai ake i te whakariterite o te maitai me te whakapai ake i nga mahi o te kowiri. Hei tauira, ko te waahanga o te hua o te 16mn ko te 40% teitei ake i te A3 maitai. Ko te kowiri kei roto i te 11-14% Manganese he tino taumaha, e whakamahia ana mo nga peere kaieke, nga raarangi mira.

4. Phosphorus (P) : I roto i te katoa, ko te phosphorus he mea kino ki te maitai, ka kaha ake te makariri o te kowhatu, ka whakahekehia te kirihou, ka pakaru te mahi makariri. Na reira, i te nuinga o te waa ka iti iho te ihirangi o te phosphorus i te kowhatu i te 0.045%, me te hiahia mo te maitai-kounga teitei.
