Te Hanganga: Ko te nui o te waro he 0.07%-0.14%, ko te nui o te silicon he 0.17%-0.37%, ā, ko te nui o te manganese he 0.35%-0.65%.
Ngā Āhuatanga: He pai te kirihou, te pakari me ngā āhuatanga whakarewa, ā, he pai mō ngā āhuatanga pēhanga me te pāmahana waenga.

Te Hanganga: Ko te nui o te waro he 0.17%-0.23%, ko te nui o te silicon he 0.17%-0.37%, ā, ko te nui o te manganese he 0.35%-0.65%.
Ngā Āhuatanga: He kaha ake, he pakeke ake, engari he iti ake te kirihou me te pakari, ā, he pai mō ngā āhuatanga pēhanga me te pāmahana teitei ake.
Whakamahia ngā horopaki
Ngā ngongo pakitara whakamatao wai o te poihau: ka tu atu ki te wera hihi o te hau pāmahana teitei i roto i te poihau, ka whakawhiti ki te wai hei hanga mamaoa, me te hiahia kia pai te ātete o ngā ngongo ki te pāmahana teitei me te ātete ki te waikura.

Ngā ngongo whakamahana nui o te kōhua: e whakamahia ana hei whakamahana anō i te mamaoa kua mākū ki roto i te mamaoa kua wera rawa, me te hiahia kia kaha te kaha me te pumau o ngā ngongo i raro i ngā āhuatanga pāmahana tiketike.

Ngā ngongo penapena pūwero: ka whakahokia mai te wera para i roto i te hau paipa, ka whakapai ake i te pai o te wera, me te hiahia kia pai te kawe wera me te ātete ki te waikura.

Ngā paipa tereina mamaoa: tae atu ki ngā paipa mamaoa wera rawa me ngā paipa wai kohua, e whakamahia ana hei tuku mamaoa pāmahana teitei me te pēhanga teitei me te wai wera, me whai kaha miihini pai ngā paipa me te ātete pāmahana teitei.

I roto i te poto,Ngā paipa maitai tui GB3087he mea nui i roto i te umanga hanga poiha pēhanga iti me te pēhanga waenga. Mā te whiriwhiri i ngā rauemi me ngā tukanga hanga e tika ana, ka taea te whakapai ake i te whai huatanga o te mahi me te haumaru o te poiha kia tutuki ai ngā hiahia o ngā āhuatanga mahi rerekē.
