maualuga maualuga carbon fausaga uamea:

Nu. 10 paipa u'amea seamless e le oi ai isi elemene u'amea (sei vagana elemene totoe) vagana carbon (C) elemene ma se aofaiga patino o le silicon (Si) mo deoxidation (masani e le sili atu nai lo 0.40%), manganese (Mn) (masani e leai. sili atu i le 0.80%, e oʻo atu i le 1.20%) elemene elemene.

O ia u'amea e tatau ona iai uma vaila'au ma mea fa'ainisinia.O mea o loʻo i totonu o le sulfur (S) ma le phosphorus (P) e masani ona pulea i lalo ole 0.035%.Afai e pulea i lalo ole 0.030%, e taʻua o le sila maualuga, ma le "A" e tatau ona faʻaopoopo pe a uma le vasega, pei ole 20A;Afai e pulea le P i lalo ole 0.025% ma le S o loʻo pulea i lalo ole 0.020%, e taʻua o le sila maualuga maualuga, ma le "E" e tatau ona faʻaopoopo pe a uma le vasega e faʻaalia ai le eseesega.Mo isi elemene alloying totoe aumaia i totonu o le uamea e ala i mea mata, e pei o le chromium (Cr), nickel (Ni), kopa (Cu), ma isi, o le anotusi o Cr≤0.25%, Ni≤0.30%, Cu≤0.25%.O nisi ituaiga o manganese (Mn) e oʻo atu i le 1.40%, ua taʻua o le manganese steel.

Nu. 10 fua fa'atatau o le mamafa o paipa u'amea:[(mamafa i fafo - mafiafia puipui)* mafiafia puipui]*0.02466=kg/m (mamafa ile mita)
