O nisi nei o manatu autu e faʻafeiloaʻi ai le 440C stainless steel pa mafolafola:
1. Fa'aputuga: 440C uamea uamea mafolafola pa e matua'i fa'apipi'iina i le chromium (16-18%), carbon (0.95-1.20%), ma le tele o isi elemene e pei o le manganese, silicon, ma le molybdenum.
2. La'ei Tetee: 440C u'amea u'amea mafolafola pa e ta'uta'ua ona o le tulaga ese le ofuina tete'e, faia talafeagai mo talosaga e aofia ai mea abrasive, tipi meafaigaluega, bearings, ma vaega e tete'e ofuina.
3. Tete'e Fa'aleaga: E ui lava i le maualuga-carbon u'amea u'amea, 440C fa'aalia lelei tete'e a'a.
4. Malosi ma Malosi: 440C uamea uamea mafolafola pa'u e sili ona maaa ma maualuga le malosi, e maua ai le tumau ma le umi i talosaga manaʻomia.
