O lo'o i ai fua fa'atatau ma calculators i luga ole laiga e faigofie ai ona fa'atatau le mamafa uamea.

Ua fa'avasegaina u'amea i lalo o le 5 vaega ma o nei mea e aofia ai le 200 ma le 300 fa'asologa o u'amea u'amea lea e ta'ua o austenitic stainless steels.Ona i ai lea o le 400 faasologa, o uʻamea uʻamea ferritic.O le 400 series ma le 500 series e taʻua o martensitic stainless steels.Ona i ai lea o ituaiga PH o uʻamea stainless, o le timu hardening vasega stainless steels.

Ma le mea mulimuli, o loʻo i ai le faʻafefiloi o uʻamea uʻamea ferritic ma austenitic, lea e taʻua o le duplex stainless steels.
