440C Pa uamea uamea
Fa'amatalaga Puupuu:
440C u'amea u'amea ose maualuga-carbon martensitic uʻamea uʻamea lea e lauiloa mo lona maaa sili ona lelei, ofuina teteʻe, ma corrosion teteʻe.
Uamea uamea 440C Pa:
440C uʻamea uʻamea e mafai ona faʻamaʻaʻaina e ausia ai tulaga maualuga o le maaa, e masani lava i le 58-60 HRC (Rockwell hardness scale). E aʻafia i le 400 faʻasologa o uʻamea uʻamea, o loʻo faʻaalia e ala i le maualuga o le carbon content, e masani lava ile 0.60-1.20% , ma le fa'afefeteina o le pala. E sili ona lelei le fa'aogaina o le ofuina, e fetaui lelei mo fa'aoga e pei o pa'u, meafaigaluega tipi, mea faigaluega tipi, ma vaega valve. E ui lava e le o le pala e pei o austenitic stainless steels (eg, 304, 316), 440C ofo atu lelei tete'e corrosion i siosiomaga malu. E sili atu le fa'afefeteina nai lo isi u'amea maualuga-carbon ona o lona chromium content.440C u'amea u'amea e mafai ona vevela-togafitia e ausia ai mea e manaʻomia masini.

Ituaiga & Faamanuiaga:
•A maeʻa togafitiga vevela talafeagai, 440C uʻamea uʻamea e mafai ona ausia se maualuga maualuga o le maaa, e masani lava i le va o le 58-60 HRC, e talafeagai mo talosaga e manaʻomia ai le malosi maualuga.
•Ona o le maualuga o le carbon content ma mea e sili ona lelei mo togafitiga vevela, 440C stainless steel o loʻo faʻaalia ai le faʻaogaina o le ofuina, e talafeagai mo faʻaoga eseese e pei o meafaigaluega tipi, bearings, ma isi.
•E ui lava e le o le pala e pei o austenitic stainless steels (faataitaiga, 304, 316), 440C uʻamea uʻamea o loʻo ofoina atu pea le faʻafefeteina lelei i siosiomaga talafeagai, muamua ona o lona maualuga chromium anotusi, lea e fausia ai se puipuiga chromium oxide luga layer.
•440C uʻamea uʻamea e mafai ona faʻaogaina lelei i lalo o tulaga talafeagai e faʻafetaui ai manaʻoga vaega eseese. Ae ui i lea, ona o le maualuga o le maaa ma le malosi, e mafai ona fai si faigata o masini ma e manaʻomia ai faiga ma meafaigaluega talafeagai.
•440C uʻamea uʻamea faʻaalia lelei maualuga-maualuga mautu, faatumauina lona maaa ma ofuina teteʻe i lalo o tulaga maualuga o le vevela, e talafeagai mo talosaga i siosiomaga maualuga-vevela.
•O mea faʻainisinia o le 440C stainless steel e mafai ona fetuʻunaʻi e ala i togafitiga vevela, e pei o le maaa, malosi, ma le faigata, e faʻafetaui ai manaʻoga faʻapitoa.
