1. Dab tsi yog lwm lub npe rau hastelloy?
"Nickel-chromium-molybdenum alloys" (piav qhia lawv thawj qhov theem pib sib xyaw).
"Kev ua tau zoo Nickel alloys" lossis "corrosion-resistant nickel superalloys" (qhia lawv cov khoom tseem ceeb).
2. Cov qib ntawm hastelloy li cas?
A. Corrosion-resistant c-Series Qib
Muaj pes tsawg: ~ 57% ni, 14.5-16.5% CR, 15-17% MO, 3-4% W, 4-7% FE.
Cov Khoom Siv Tseem Ceeb: Kev tiv thaiv zoo heev rau kev txo qhov chaw ib puag ncig (xws li sulfuric acid, hydrogen chloride) thiab chloride pitting. Dav siv hauv kev ua tshuaj, roj thiab roj, thiab kev tswj kev paug.
Muaj pes tsawg: ~ 56% ni, 20-22% cr, 12-14% mo, 2.5-3,5% w, 2-6% FE.
Cov Khoom Siv Tseem Ceeb: Zoo siab chromium cov ntsiab lus txhim kho kom tsis kam rau oxidizing ib puag ncig (piv txwv li, nitric acid, hypochlorites) thiab cov acids. Zoo dua rau C-276 hauv pitting / Crevice corrosion tsis kam nyob hauv chloride-nplua nuj chaw.
Muaj pes tsawg: ~ 59% ni, 23-27% cr, 15-17% mount, 1-2% CU,.
Cov Khoom Siv Tseem Ceeb: Cov Ntsuas Hluav Taws Xob Cov Hluav Taws Xob (oxidizing tawm tsam) thiab molybdenum (txo kev tawm tsam) nrog tooj liab ntxiv rau cov sulfuric acid kev ua tau zoo. Siv nyob rau hauv kev txhoj puab heev.
Muaj pes tsawg: ~ 65% ni, 14-18% cr, 14-17% MO, NCO.
Cov Khoom Siv Tseem Ceeb: Cov ntsiab lus hlau tsis muaj roj av thiab cov ntsiab lus carbon minimizes carbide nag lossis kev txhim kho kev ruaj khov hauv cov nroj tsuag hluav taws xob siab (piv txwv li cov nroj tsuag acid).
B. Kev kub-kub thiab oxidation-resistant cov qib
Muaj pes tsawg: ~ 47% ni, 20.5-23.5% CR, 8-10 -5% MO, 0.5-25% W, 17-20% FE.
Cov Khoom Siv Tseem Ceeb: Koj lub zog zoo thiab oxidation tiv thaiv nyob rau ntawm qhov kub (txog li 1,200 ° C). Siv nyob rau hauv cov av turbine Cheebtsam, rauve qhov chaw, thiab kev pauv hluav taws xob.
Muaj pes tsawg: ~ 43% NI, 28-31% CR, 4-6% MO, 1.5-4% CU, 15-20% FE.
Cov Khoom Siv Tseem Ceeb: Sib koom siab chromium siab (oxidation tsis kam lees) nrog molybdenum thiab tooj (acid tsis kam). Qhov zoo tagnrho rau cov tshuaj lom neeg mob siab thiab cov roj ruulfurization.
C. Lwm cov qib tshwj xeeb
Muaj pes tsawg: ~ 65% ni, 26-30% MO, 50% FE, ≤1% CR.
Cov Khoom Siv Tseem Ceeb: Zoo tshaj qhov tsis kam rau txo cov kua qaub (piv txwv li hydrochloric, sulfuric, thiab cov sulfuric) tab sis tsis zoo hauv oxidizing ib puag ncig. Siv nyob rau hauv pickling tso tsheb hlau luam thiab cov tshuaj reactors.
Txhim kho version ntawm B-2: Zoo dua thermal ruaj khov thiab tiv taus pitting hauv chloride daws teeb meem.
Muaj pes tsawg: ~ 72% ni, 6-8% CR, 16-18% MO, 4-6% FE.
Cov Khoom Siv Tseem Ceeb: Tsim rau molten fluoride fluoride purpen ib puag ncig (piv txwv li, nuclear reactors) nrog high-kub ruaj khov.
