HASTELLOYC4o se u'amea e aofia ai Nickel, chromium, ma molybdenum. E fa'asilisiliina o le u'amea pito sili ona lelei mo le fa'afefe o le pala. O lenei u'amea e fa'aalia ai le tete'e atu i le fa'atupuina o le fa'atupuina o le saito e fa'afefeteina pe a o'o i le fa'afefe o le vevela, ma fa'afaigofie ai mo le fa'aogaina o vaila'au eseese i lona tulaga uelo. E le gata i lea, AlloyC4fa'aalia le tete'e mata'ina i pitting, ta'e fa'amamafa-corrosion, ma ea fa'ama'i e o'o atu i le 1900°F. E iai lona tete'e fa'apitoa i le tele o si'osi'omaga vaila'au.
TALOSAGA:
1. Alamanuia pepa: Digesters ma laau pisapisao.
2. Si'osi'omaga kasa oona: Vaega fa'aalia i kesi oona.
3.Flue-gas desulfurization laau: Meafaigaluega e faʻaaogaina i le faʻafefe-kasa desulfurization laau.
4.Sulfuric acid environments: Evaporators, fa'afefe vevela, filiga, ma mea fa'afefiloi e fa'aaogaina i siosiomaga sulfuric acid.
5.Sulfuric acid reactors: Meafaigaluega o loʻo faʻaaogaina i le sulfuric acid reactors.
6. Organic chloride process: Meafaigaluega faʻaaogaina i le faʻaogaina o le chloride faʻasolosolo.
7. Halide po'o fa'agaio'iga fa'aoso: Meafaigaluega e fa'aogaina i faiga e fa'aogaina ai mea fa'apipi'i po'o fa'ama'i.
