Hastelloy C-276 u'amea ose tungsten-o lo'o i ai nickel-chromium-molybdenum alloy, lea e manatu o se u'amea fa'afefete tele ona o lona maualalo silicon carbon anotusi.
E masani lava ona tetee i chlorine susu, eseese oxidizing "chlorides", chloride masima fofo, sulfuric acid ma oxidizing masima.O lo'o i ai le fa'a'ele'ele lelei i le maualalo ma le feololo le vevela o le hydrochloric acid.

1. Lelei le fa'afefeteina i le tele o ala fa'asalalau i le tulaga o le fa'ama'iina ma le fa'aitiitia.
2. sili ona tetee i le pala, crevice corrosion ma le atuatuvale corrosion ta'e performance.C276 uʻamea e talafeagai mo alamanuia faagasologa vailaau eseese o loo i ai oxidation ma faaitiitia media.High molybdenum, chromium anotusi i alloy faaalia tetee i chloride ion tafia, ma elemene tungsten foi faaleleia atili. lona corrosion resistance.C276 ua na o se tasi o nai mea e mafai ona faaalia tetee i chlorine susu, hypochlorite ma chlorine dioxide fofo corrosion, ma faaalia taua tetee corrosion i le maualuga concentration chlorate solution (e pei o ferric chloride ma apamemea chloride).
Faʻaaogaina lautele i le matata o vailaʻau ma petrochemical, e pei o le faʻaogaina i vaega faʻaola o loʻo i ai le chloride ma catalytic system, aemaise lava mo le maualuga o le vevela, inorganic acid ma organic acid (e pei o le formic acid ma le acetic acid) faʻafefiloi ma mea leaga, siosiomaga faʻafefe vai. .
Faʻaaogaina e tuʻuina atu i le tulaga o meafaigaluega autu nei poʻo vaega:
1. Alamanuia pulupulu ma pepa, e pei o le kuka ma le fagu pa'u.
2. O le olo fufulu o le FGD system, fa'avevela, toe su'e ausa susu.
3. Le faʻaogaina o meafaigaluega ma vaega i totonu o le siosiomaga kesi acidic.
4. Acetic acid ma acid reactor;5.Sulfuric acid condenser.
6. Methylene diphenyl isocyanate (MDI).
7. E le mama phosphoric acid gaosiga ma gaioiga.
