Hastelloy C-276® o se nickel-molybdenum-chromium alloy faʻatasi ai ma le sili ona lelei le faʻafefeteina i siosiomaga ogaoga.O le maualuga o le nickel ma le molybdenum mea e maua ai le u'amea u'amea nickel aemaise lava e tetee atu i pitting ma clevice corrosion i le faʻaitiitia o siosiomaga aʻo faʻaalia e le chromium le tetee i faʻasalalauga faʻamaʻi.E ui lava o loʻo i ai le tele o fesuiaiga o le Hastelloy nickel alloy, Hastelloy C-276 e sili atu ona faʻaaogaina lautele.
Aotelega o uiga o Hastelloy C-276:
Hastelloy C-276 (N10276) e sili ona lelei le fa'afefeteina i le tele o fa'asalalauga i lalo o le fa'ama'iina ma le fa'aitiitia o tulaga.E sili atu le tete'e atu i le fa'a'a'a'a, ma'a ma'a ma fa'amamafa ta'ei.O le u'amea e talafeagai mo le tele o alamanuia fa'agasologa o vaila'au o lo'o iai fa'ama'i fa'ama'i ma fa'aitiitia fa'asalalauga.O le maualuga o mea o loʻo i totonu o le molybdenum ma le chromium e mafai ai ona faʻasaʻo le uʻamea i le pala e chloride ions, ma o le elemene tungsten e faʻaleleia atili ai lona teteʻe.
Hastelloy C-276 o se tasi o mea e mafai ona tetee atu i le pala o chlorine susu, hypochlorite ma chlorine dioxide solution.O le u'amea o lo'o i ai le malosi tele e tetee atu ai i vaifofo masima chlorinated (e pei o le chlorinated Iron ma le copper chloride).
