HastelloyC u'amea o se u'amea sili Ni-Cr-Molybdenum-Tungsten e ofoina atu le sili atu le fa'afefete fa'a'a'ala'au nai lo isi o lo'o iai Ni-Cr-Molybdenum-Hatelloy C276, C4 ma 625 alloys.
O u'amea a Hastelloy C e lelei tele le tete'e atu i pitting, fa'a'a'a ma fa'amamafa ta'ei.
E sili ona tete'e i le fa'ama'iina o le vai, e aofia ai le chlorine susu, nitric acid po'o le fa'afefiloi o vaila'au fa'ama'i o lo'o iai ion chloride.
I le taimi lava e tasi, o loʻo i ai foi i le Hastelloy C alloys le malosi lelei e tetee atu ai i le faʻaitiitia ma le faʻamaʻiina o siosiomaga e feagai ma le faagasologa.
Faatasi ai ma lenei agavaʻa, e mafai ona faʻaaogaina i nisi o siosiomaga faʻalavelave, poʻo fale gaosi oloa mo le tele o faʻamoemoega gaosiga.
Hastelloy C alloy e matua tetee atu i siosiomaga vailaʻau eseese, e aofia ai mea faʻamaʻi malosi, e pei o le ferric chloride, copper chloride, chlorine, vaifofo faʻaleagaina (organic poʻo le inorganic), formic acid, acetic acid, acetic anhydride, suasami ma vai masima.
Hastelloy C alloy e iai le malosi e tete'e ai le fa'atupuina o timuga o saito i totonu o le sone e a'afia ai le vevela, lea e talafeagai ai mo le tele o ituaiga o fa'agasologa o vaila'au i le setete uelo.
