400 Fa'asologa-Ferritic ma Martensitic uamea uamea
Ituaiga 408-Le lelei le faʻafefeteina o le vevela, vaivai faʻafefete, 11% Cr, 8% Ni.
Ituaiga 409-le ituaiga sili ona taugofie (Peretania-Amerika), e masani ona faʻaaogaina e pei o paipa taʻavale taʻavale, o se uʻamea uʻamea ferritic (chrome steel).
Ituaiga 410-Martensite (maualuga chromium uʻamea maualuga), lelei le ofuina o laei ma le leaga o le pala.
Ituaiga 416-Faʻaopoopo sulfur faʻaleleia le gafatia o faʻamatalaga.
Ituaiga 420- "vaega lau" martensitic sila, tutusa ma le sila stainless muamua o Brinell chromium maualuga sila. Faʻaaogaina foi i naifi tipitipi, e mafai ona matua susulu.
Ituaiga 430-ferritic stainless steel, mo teuteuga, e pei o mea tau taavale. Matagofie moldability, ae leaga le vevela tetee ma corrosion tetee.
Ituaiga 440-maualuga-malosi meafaigaluega tipi uʻamea, lea o loʻo i ai sina carbon maualuga maualuga, e mafai ona maua le malosi maualuga maualuga pe a maeʻa togafitiga vevela talafeagai, ma o le maaa e mafai ona oʻo atu i le 58HRC, lea e faʻavasegaina o le uʻamea sili ona faigata. O le fa'aoga masani o, mo se fa'ata'ita'iga, o le "seula". E tolu ituaiga masani: 440A, 440B, 440C, ma le 440F (faigofie ona fa'agasolo).
