1. Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm cov nickel alloy tuav?
Teb:
Inconel 718: Nickel ~ 50-55%, Chromium 17-21%, Hlau ~ 17%, Niobium 4-5%, Molybdenum 2.8-3.3%
Inconel 625: Nickel 58% min, Chromium 20-23%, Molybdenum 8-10%, Niobium + Tantalum 3.15-4.15%
Hastelloy C-276: Nickel 57% min, Molybdenum 15-17%, Hlau 5% max, Chromium 15-17%
Monel 400: Nickel 63%, Copper 28-34%, Hlau 2.5%, Manganese 2%
Cov khoom sib xyaw no muab kev tiv thaiv corrosion zoo heev, siab - qhov kub thiab txias, thiab ua haujlwm ntev hauv qhov chaw hnyav.
2. Dab tsi yog cov ntawv thov ntawm cov hlau nplaum no?
Teb:
Inconel 718 & 625: Aerospace, roj turbines, siab - kub fasteners, nuclear Cheebtsam
Hastelloy C-276: Kev ua tshuaj lom neeg, khoom siv tswj kev ua qias tuaj, ib puag ncig hauv hiav txwv, thiab cov kab mob acid-resistant
Monel 400: Marine hardware, twj tso kua mis, li qub, khoom siv hauv kev lag luam tshuaj, thiab kev siv dej hiav txwv
3. Cov kab no puas tuaj yeem txiav, khoov, lossis welded yam tsis muaj kev cuam tshuam?
Teb:
Kev txiav: tuaj yeem ua tiav siv cov hlua khi, ntshav, lossis dej dav hlau. Kev noj qeeb qeeb tau pom zoo kom tsis txhob ua haujlwm hnyav.
Khoov: Ua tau tom qab cua sov rau cov hlau xws li Inconel 718 lossis C-276; Monel 400 tuaj yeem txias-khoov vim ductility.
Vuam: TIG, MIG, los yog tsis kam welding yog pom zoo nrog cov muab tub lim sib haum; preheating tej zaum yuav xav tau rau siab -lub zog alloys zoo li Inconel 718.
Cov txheej txheem tsim nyog khaws kev tiv thaiv corrosion thiab mechanical kev ncaj ncees.
4. Cov khoom siv dab tsi tuaj yeem xav tau los ntawm cov kab no?
Teb (tus nqi ib txwm):
Inconel 718: Tensile zog ~ 1,240 MPa, Tawm zog ~ 1,030 MPa, Elongation 12-20%
Inconel 625: Tensile zog 827 MPa, Tawm zog 414 MPa, Elongation 30-40%
Hastelloy C-276: Tensile zog 483 MPa, Tawm zog 207 MPa, Elongation 40%
Monel 400: Tensile zog 550-690 MPa, Yield zog 240-380 MPa, Elongation 30-50%
5. Cov qauv no ua tau raws li cov txheej txheem alloy?
Teb:
ASTM B637 / B670 / B443 / B444 / B366 / B162 - Nyob ntawm hom alloy, rau tuav, forgings, lossis rods
UNS cov npe: N07718 (Inconel 718), N06625 (Inconel 625), N10276 (Hastelloy C-276), N04400 (Monel 400)
Cov qauv no ua kom muaj tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov ntev ua tau raws li cov kev xav tau ntawm kev lag luam rau kev ua haujlwm siab -.
