Fa'asologa o vasega, mea fa'ainisinia ma fa'amatalaga o gaosiga o lo'o pulea e le tele o tulaga fa'ava-o-malo ma tulaga fa'ale-atunu'u mo u'amea u'amea.A'o fa'aoga masani le fa'avasegaina o togi u'amea fa'ailoga uamea e tolu-numera (eg 304 ma le 316).
O nei faiga e aofia ai le 1-mataitusi + 5-numera UNS, pei o le S30400, e pei ona faʻamatalaina e le SAE ma le ASTM.O atunuu Europa o loʻo faʻaaogaina tulaga faʻavae masani Euro.O nei atunuu o loʻo suitulaga pe fetuutuunai a latou lava atunuʻu tulaga faʻapitoa e faʻataʻitaʻia ai tulaga masani a le Euro.O isi fa'ailoga ua suia e aofia ai numera tuai BS ma EN pei ole 304S31 ma le 58E.
O nisi togi e le o aofia i numera masani ma e mafai ona avea ma togi fa'apitoa pe fa'aigoaina e fa'aaoga ai tulaga fa'apitoa mo oloa fa'apitoa e pei o uaea uelo.
Fa'ata'ita'iga u'amea u'amea o lo'o fa'amatalaina au'ili'ili ile British Stainless Steel Association "Ta'iala i Fa'amatalaga Fa'amatalaga u'amea", e ta'ua fo'i o le BSSA "Blue Guide".
O le laulau o loʻo i lalo o loʻo lisiina ai le tele o togi uamea, o latou igoa tuai BS, numera UNS fou ma le igoa EN fou.

E le iloa e le ASTM ia fa'ailoga i puipui.E tele isi togi ma fa'amatalaga o lo'o avanoa.
O mea na tuʻuina atu e le Jindalai Steel Group ua gaosia ina ia tausisia le tele o tulaga faʻatatau i le oloa.E aofia ai fo'i tulaga fa'auma o mea.
Jindalai Steel Group- o le taʻutaʻua o le gaosiga o le uamea i Saina.A'afiaga i luga o le 20 tausaga o atina'e i maketi faava o malo ma o lo'o i ai nei 2 fale gaosi oloa ma le gaosiga gafatia e sili atu i le 400,000 tone i tausaga ta'itasi.Afai e te manaʻo e maua nisi faʻamatalaga e uiga i mea uʻamea uʻamea, faʻafeiloaʻi e faʻafesoʻotaʻi i matou i le asō pe talosagaina se upusii.
