Dab tsi yog acid-resistant, Hastelloy lossis 316L stainless hlau?
Hastelloy yog corrosion-resistant, tab sis ntawm chav kawm tus nqi yog ntau dua 316L, yog li cov kev ua hauj lwm thiab cov nqi yuav tsum tau txiav txim siab.
Hastelloy qib: Hastelloy C276, Hastelloy C22, Hastelloy C-2000, Hastelloy C-4, Hastelloy C, Hastelloy B, Hastelloy B-2, Hastelloy B-3, Hastelloy X, Hastelloy G-30, Hastelloy G-35, thiab lwm yam.
Nov yog qee qhov kev siv dav dav:
Feem ntau siv Hastelloy C-276 Hastelloy, nickel-chromium-molybdenum alloy, tiv taus kub thiab corrosion.
Txheej txheem cej luam ntawm Hastelloy C-276 yam ntxwv thiab daim ntawv thov teb:
Cov hlau no muaj kev tiv thaiv zoo heev rau feem ntau cov xov xwm corrosive hauv ob qho tib si oxidized thiab txo cov xeev. Kev tiv thaiv zoo heev rau pitting corrosion, crevice corrosion thiab kev nyuaj siab corrosion cracking. Lub alloy yog tsim rau siv nyob rau hauv ntau yam kev lag luam chemical industries uas muaj oxidizing thiab txo cov xov xwm. Qhov siab dua molybdenum thiab chromium cov ntsiab lus ua rau cov hlau resistant rau chloride ion yaig, thiab cov khoom tungsten ntxiv txhim kho nws cov corrosion kuj. Hastelloy C-276 yog ib qho ntawm cov khoom siv nkaus xwb uas tiv taus corrosion los ntawm cov tshuaj chlorine moist, hypochlorite thiab chlorine dioxide daws. Cov alloy muaj qhov tseem ceeb corrosion tsis kam rau siab concentration ntawm chloride ntsev tov (xws li chlorine hlau thiab tooj liab chloride).
Hastelloy C-276 qib zoo sib xws:
W.Nr.2.4819 NiMo16Cr15W (Lub Tebchaws Yelemees) NC17D (Fabkis)
Hastelloy C-276 metallographic qauv:
Lub alloy muaj lub ntsej muag-centered cubic lattice qauv.
Hastelloy C-276 txheej txheem kev ua tau zoo thiab cov cai:
1. Qhov qis dua cov sulfur cov ntsiab lus hauv thermal ua roj, qhov zoo dua. Cov ntsiab lus sulfur hauv cov pa roj yuav tsum tsawg dua 0.1%, thiab cov ntsiab lus sulfur hauv cov roj hnyav yuav tsum tsawg dua 0.5%.
2. Lub thermal ua haujlwm kub ntau ntawm cov hlau yog 1200 degree ~ 950 degree, thiab cov txheej txheem txias yog dej txias lossis cua txias sai.
3. Haum rau txhua yam txheej txheem vuam, xws li tungsten electrode inert gas shielded vuam, plasma arc vuam, phau ntawv sub-arc vuam, hlau ncej inert roj shielded vuam, thiab melting ncej inert roj shielded vuam.
