1. Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm cov nickel alloy kav thiab cov kav dej?
Teb:
Hastelloy C-276: Nickel 57% min, Chromium 15-17%, Molybdenum 15-17%, Hlau Tsawg dua lossis sib npaug li 5%, Cobalt Tsawg dua lossis sib npaug li 2.5%
Hastelloy C-22: Nickel 56% min, Chromium 20-22%, Molybdenum 12-14%, Hlau Tsawg dua lossis sib npaug li 4%
Inconel (qib zoo li 600/625): Nickel 58–72%, Chromium 14–23%, Hlau 6–17%, Molybdenum / Niobium nyob ntawm qib
Monel 400: Nickel 63%, Copper 28-34%, Hlau 2.5%, Manganese 2%
Monel 600: Nickel 60-65%, Copper 28-34%, Hlau 2.5%, Manganese 2%
Cov khoom sib xyaw no muab kev tiv thaiv corrosion zoo heev, tshuaj lom neeg ruaj khov, thiab ua haujlwm siab - kub.
2. Dab tsi yog qhov kev siv tseem ceeb ntawm cov kav dej thiab cov kav hlau?
Teb:
Hastelloy C-276 / C-22: Cov cuab yeej siv tshuaj lom neeg, tshuaj tua hluav taws xob, cov kua qaub tuav, tswj cov pa phem
Cov kav dej Inconel: Aerospace, roj turbines, nuclear nroj tsuag, siab -kub piping
Monel 400/600 tubes: Marine daim ntaub ntawv, seawater piping, twj, li qub, tshuaj thiab hydrocarbon ua
3. Cov hlau thiab cov kav dej no puas tuaj yeem tsim tau (txiav, khoov, welded) yooj yim?
Teb:
Kev txiav: tuaj yeem ua tiav siv band saw, plasma, laser, lossis dav hlau dej. Kev qeeb qeeb tau pom zoo kom tsis txhob ua haujlwm hnyav.
Khoov: Monel 400 thiab 600 tuaj yeem txias - khoov; Inconel thiab Hastelloy tuaj yeem xav tau cua sov rau kev khoov nruj.
Vuam: TIG, MIG, thiab arc vuam yog ua tau nrog cov muab tub lim sib haum. Preheating tej zaum yuav xav tau rau qee qhov siab - lub zog alloys kom tsis txhob tawg.
Kev tsim kom zoo ua kom cov neeg kho tshuab kev ncaj ncees thiab kev tiv thaiv corrosion raug tswj xyuas.
4. Cov khoom siv kho tshuab dab tsi tuaj yeem xav tau los ntawm cov raj thiab cov kav dej?
Teb (tus nqi ib txwm):
Hastelloy C-276: Tensile zog 483 MPa, Tawm zog 207 MPa, Elongation 40%
Hastelloy C-22: Tensile zog 517 MPa, Tawm zog 241 MPa, Elongation 40%
Inconel 625: Tensile zog 827 MPa, Tawm zog 414 MPa, Elongation 30-40%
Monel 400: Tensile zog 550-690 MPa, Yield zog 240-380 MPa, Elongation 30-50%
Monel 600: Tensile lub zog 550-620 MPa, Yield zog 220-380 MPa, Elongation 30-50%
5. Cov kav dej thiab cov kav hlau alloy no ua raws li cov qauv dab tsi?
Teb:
ASTM Cov Qauv:
ASTM B444 / B366 - Nickel Alloy thiab Inconel raj
ASTM B622 / B861 - Hastelloy C-276 / C-22 raj thiab kav
ASTM B164 / B127 - Monel 400/600 raj
UNS Cov Npe:
N10276 (Hastelloy C-276), N06022 (Hastelloy C-22), N06625 (Inconel 625), N04400 (Monel 400), N06600 (Monel 600)
Kev ua raws cai ua kom ntseeg tau tias kev ua tau zoo nyob rau hauv siab - corrosion, siab - kub, thiab ib puag ncig marine.
