O u'amea lamolemole o u'amea maualuga ia o lo'o i ai le maualuga o le pala e fa'atusatusa i isi u'amea ona o le tele o le chromium. Faʻavae i luga o latou fausaga tioata, ua vaevaeina i ni ituaiga se tolu e pei o ferritic, austenitic, ma martensitic steels. O le isi vaega o u'amea u'amea o u'amea fa'ama'a'a. O latou o se tuufaatasiga o uamea martensitic ma austenitic.
Vasega 440C u'amea u'amea ose maualuga carbon martensitic uamea. E i ai le malosi maualuga, fa'afefeteina feololo, ma lelei ma'a'a ma ofuina tete'e. Vasega 440C e mafai ona maua, pe a maeʻa togafitiga vevela, le malosi sili ona maualuga, maʻaʻa ma le faʻaogaina o le faʻaogaina o uʻamea uma. O lona maualuga maualuga o le carbon content e nafa ma nei uiga, lea e faʻapitoa ai le 440C i mea faʻaoga e pei o polo ma vaega valve.
