Momo o te waro maitai:
maitai Carbon ko tetahi o rauemi matua i roto i te ao o castings maitai. Ka taea te whakarōpūtia steels waro ki ngā momo i raro nei:
steels iti-waro (<0.20% C): whakahere i te whānuitanga o ngā āhuatanga kurut mā maimoatanga wera, me te taea te whakapakeketia ki hoatu pakeke mata tiketike ki abrasion resistance me te kōngohe matua pai.
Steels Waenga-waro (0.20 ki te 0.50% C): taea tenei hanganga ki reira kia atu roa, e ngawari noa, me kaha. He whānui o ngā kaha kurut e taea ki te ukanga pai, me te ru ātete, ngā machined i roto i te huru fakavaivaí.
Steels High-waro (> 0.50% C): Kaha, me te kua he mahara āhua pai, hanga ana e ia he kōwhiringa tino whai hua mō ngā kaiwhakanao puna. Tenei parahi koranu mō tono kurut tiketike he kaupapa ki te kakahu me te abrasion me he tika ana mō ngā tono taimaha-ohipa rite te pai.
Hua o Waro Steel castings
waro maitai ko te kōwhiringa rauemi tino rongonui mō castings maitai, i te mea he whānui nui o ngā tono i roto i te maha ngā ahumahi rerekē. Hoki te utu rauemi iti, me te momo o ngā auroro rauemi, kei te whakamahia waro maitai te whakarewanga o me taea te whakapai ake tona kaha, te ukanga me te tahi atu mahi i te maimoatanga wera mō ngā tono ahumahi.
