O uiga autu o le 310 paipa uamea e: maualuga le vevela, e masani ona faʻaaogaina i fagu ma paipa taʻavale, ma isi mea totino e averesi.
303 paipa uʻamea uʻamea: E ala i le faʻaopoopoina o se vaega itiiti o le sulfur ma le phosphorus, e sili atu ona faigofie ona tipi ma faʻagasolo nai lo le 304. O isi mea totino e tutusa ma le 304 uamea faʻafefeteina paipa.
302 paipa u'amea u'amea: 302 u'amea u'amea ua fa'aaogaina lautele i vaega ta'avale, va'alele, meafaigaluega meafaigaluega aerospace, ma alamanuia vaila'au. O faʻamatalaga o loʻo taua i lalo: galuega taulima, faʻamau, faʻasologa faʻasolosolo, mea faʻafomaʻi, mea eletise, ma isi uiga: 302 polo uʻamea uʻamea o se uʻamea austenitic, lea e latalata i le 304, ae o le maaa o le 302 e maualuga atu, HRC≤28, ma e lelei le ele ma le pala.
301 uamea uamea uelo paipa: ductility lelei, faʻaaogaina mo oloa gaosia. E mafai foʻi ona faʻamaʻa vave e ala i le faʻaogaina o masini ma e lelei le faʻaogaina. La'ei tete'e ma le vaivai malosi e sili atu nai lo le 304 paipa uamea.
202 paipa u'amea u'amea: O se chromium-nickel-manganese austenitic u'amea u'amea ma sili atu le faatinoga nai lo 201 u'amea.
