Hastelloy C2000 yog ib hom tshiab ntawm Ni-Cr-Mo alloy.Raws li C4 alloy, cov ntsiab lus ntawm chromium yog txhim kho, thiab qhov sib ntxiv ntawm tooj liab zoo heev txhim kho oxidation tsis kam thiab corrosion muaj peev xwm ntawm kev txo nruab nrab ntawm cov hlau.Hastelloy C2000 yog tam sim no cov hlau alloys zoo corrosion kuj ntawm H2SO4, tab sis intercrystalline corrosion kuj tsis zoo li C4 alloy.

Corrosion kuj suav nrog sulfuric acid hydrochloric hydrofluoric acid phosphate organic chlorine alkali hlau crevice corrosion pitting, kev nyuaj siab corrosion cracking.
C-2000 alloy qhia tau hais tias zoo dua rau pitting thiab crevice corrosion tshaj C-276 alloy cov qauv kev lag luam.
Vuam thiab machining formability ntawm Hastelloy C-2000 uas zoo ib yam li C276, daws qhov teeb meem ntawm lub alloy tsim.
Kev tiv thaiv zoo heev rau kev txo qis ib puag ncig yam tsis muaj kev cuam tshuam kev ruaj ntseg ntawm metallurgy ua ke nrog siab chromium thiab cov ntsiab lus ntawm molybdenum thiab tooj liab.
• Cov txheej txheem tshuaj lom neeg kev lag luam reactor, kub exchanger, kab, thiab cov yeeb nkab.
• Kev lag luam kws tshuaj reactor thiab tshuab ziab khaub ncaws.
•Flue gas desulfurization system.
