Pa'u pauta u'amea u'amea vaega fausaga, e pei o le fa'aaogaina o mea e fa'ameamea ai le pauta 304L e fai ai vaega mo masini fufulu ipu ma masini fufulu, 316L mea fa'ameamea fa'ameamea e fai ai papatusi tulei-i fafo mo mea fai aisa, ma 410L mea fa'ameamea e fai ai ki fa'atapula'a ma pipi'i mo fufulu fale Pa'u metallurgy apamemea-fa'avae alloys o lo'o fa'aaogaina lautele foi i masini ipu, fa'agogo lavalava, masini fufulu, su'isu'i, fa'amama mama, pusaaisa, mea fa'afefiloi mea'ai ma ili eletise.

O le alamanuia o masini tamea o lo'o masani lava i le taimi nei o masini fufulu otometi.O masini fufulu otometi atoa i le taimi nei i luga o le maketi ua vaevaeina i ni vaega se tolu: o le masini taele pito i luma o le faitotoa pito i luma na fausia i Europa, o le masini fufulu pito i luga na fatuina e tagata Asia, ma le masini tamea na fausia i Amerika i Matu."Stirring" masini fufulu, lea e tele vaega e fa'aogaina ai le pauta, ma o lo'o iai fo'i fa'ata'ita'iga o le suia o vaega uamea i vaega u'amea pauta.Mo se faʻataʻitaʻiga, o le United States General Electric Company e tipiina le lua o faʻasalalauga o masini tamea otometi "faʻaoso".Vaega u'amea: faagaau loka ma paipa vili, toe mamanuina i vaega pauta metallurgy, faaleleia tau gaosiga ma le lelei o oloa, ma faaitiitia tau gaosiga mo meafaitino, galuega, tau pulega, ma otaota gau, ma le aofaiga o tupe teu faaletausaga Sili atu i le $250,000.
