440—Maualuga-malosi tipiina mea faigaluega uʻamea ma teisi maualuga carbon mea. A maeʻa togafitiga vevela, e mafai ona maua le malosi maualuga. O le maaa e mafai ona oʻo i le 58HRC, o loʻo i totonu o uʻamea sili ona faigata ona faʻamimoni. O le faʻataʻitaʻiga sili ona taatele talosaga o "razor blades". E tolu faʻataʻitaʻiga masani faʻaaogaina: 440A, 440B, 440C, ma le 440F (faigofieituaiga gaosi).
Mataupu Faavae o le silasila uʻamea polo:
E leʻo pala-faʻamaoniga ni polo uʻamea, ae le faigofie ona ele. O le faʻavae e ala i le faʻaopopoina o le chromium, o le mafiafia o le chromium oxide layer na faia i luga o le uʻamea, e mafai ai ona poloka poloka le toe faʻafesoʻotaʻi i le va o le uʻamea ma le ea, ina ia le okesene i le ea e le mafai ona ulufale i le sila. polo, ma taofia ai le aafiaga o uʻamea polo elea.
China National Standards (CNS), Japanese Industrial Standards (jis) ma le American Iron and Steel Institute (AISI) o loʻo faʻaaoga ni numera se tolu e faʻailoa mai ai eseʻesega uʻamea, o loʻo taʻua lautele i le pisinisi, o le 200 faʻasologa o le chromium-nickel-manganese -based austenitic Stainless steel, 300 series is chromium-nickel austenitic stainless steel, 400 series chromium stainless steel (e masani ona faʻaigoaina o le stainless iron), e aofia ai le martensite ma le ferrit.
