1. Dab tsi yog cov tseem ceeb ntawm cov nickel - raws li alloys (incoloy, Monel, hastelloy)?
Teb:
All these alloys belong to the nickel-based corrosion- and heat-resistant family, designed for demanding industrial environments:
Incoloy 800/825: Ua kom zoo heev rau oxidation thiab carburization ntawm cov kub, nrog lub zog zoo thiab corrosion tsis kam nyob rau hauv acidic media.
Inconel 600/718: Super zoo siab - kub oxidation tsis kam thiab siab tensile, nkag, thiab qaug zog.
Monel 400/40 / K500: Nickel -} tooj liab alloys nrog kev ua tau zoo rau dej hiav txwv thiab alkalis; K500 Ntxiv Aluminium thiab Titanium rau lub zog siab dua.
Hastelloy C276: Tshwj xeeb tsis kam rau muaj cov oxidizers muaj zog, chlorides, thiab sib xyaw acid.
Txhua tus yog tsim nyog rau huab cua sov dhau, siab, thiab tshuaj lom neeg raug.
2. Dab tsi yog lawv cov tshuaj lom neeg muaj pes tsawg leeg?
| Hlau | Qhov tseem ceeb muaj pes tsawg leeg (wt%) | Cov Ntsiab Lus Tseem Ceeb |
|---|---|---|
| Incoloy 800 | NI 30-35, CR 19-23, Fe tshuav | Ti, al |
| Incoloy 825 | Ni 38-46, cr 19.5-23.5, Mo 2.5 | CU, ti |
| Inconel 600 | Ni ntau dua lossis sib npaug rau 72, cr 14-17, Fe 6-10 | – |
| Inconel 718 | Ni 50-55, cr 17-21, nb + ta 5.1 | Mo, ti, al |
| Monel 400 | Ni 63, cu 28-34 | Fe, mn |
| Monel K500 | Ni 63, Cu 27-33 | Al, ti |
| Hastelloy C276 | Ni tshuav nyiaj, cr 14.5-16.5, Mo 15-17 | W, FE, CO |
Txhua qhov tag nrho cov nyiaj tshuav ntawm npib tsib xee, chromium, thiab tooj liab nws tsis kam, oxidation, thiab corrosive tshuaj.
3. Dab tsi yog cov neeg kho tshuab cov khoom siv ntawm cov nickel alloys (anealed mob)?
| Hlau | Tensile lub zog (mpa) | Yield zog (mpa) | Elongation (%) | Max Temp (degree) |
|---|---|---|---|---|
| Incoloy 800 | 550 | 240 | 30 | 1100 |
| Incoloy 825 | 690 | 300 | 30 | 540 |
| Inconel 600 | 655 | 240 | 35 | 1175 |
| Inconel 718 | 965 | 720 | 25 | 700 |
| Monel 400 | 550 | 240 | 35 | 480 |
| Monel K500 | 960 | 690 | 25 | 480 |
| Hastelloy C276 | 790 | 355 | 40 | 1040 |
Tag nrho cov alloys tswj lub zog siab thiab ruaj khov thoob plaws ntau qhov ntau.
4. Dab tsi yog qhov muaj qhov ntev, cov ntaub ntawv, thiab saum npoo av?
Cov Ntawv: Round Bar, tiaj li bar, Hex, pas nrig, phaj, ntawv, sawb, raj
Qhov loj me me: 1 hli - 500 hli txoj kab uas hla (lossis tuab)
Ntev: Txog 6,000 hli (kev cai txiav -- ntev muaj)
Nto tas:
Kaj / polished
Dub / pickled
Muab / tev / av
Txias drawn lossis kub dov
Mob: tag nrho annealed (daws kho thiab descaled)
5. Dab tsi yog qhov tseem muaj kev lag luam tseem ceeb ntawm cov nickel alloys?
Cov ntawv thov suav nrog:
Aerospace & Lub Hwj Pwm tiam
Tshuaj lom neeg & petrochemical ua: kev hloov pauv cua sov, cov hlab cua siab, cov tso tsheb hlau luam yeeb, cov tshuaj tiv thaiv reactor (ECOLOY 825, C276).
Tubrog nkoj thiab ntug hiav txwv: dej hiav txwv kav dej, twj tso kua mis shaft, valve Cheebtsam (Monel 400, K500).
Kev lag luam nuclear: Roj cladding, kev hloov cua sov, thiab cov tub ntxhais txhawb (incolel 600, Incoloy 800).
Cov kuab paug tswj thiab acid ntau lawm: nqus, txhuam, ductions (Hastelloy C276).
Cov alloys muab cov kev sib xyaw ua ke ntawm corrosion tsis kam, siab lub zog, oxidation tsis kam, thiab thermal ruaj khov rau ib puag ncig hnyav.
