Nov yog tsib lo lus nug thiab lawv cov lus teb txog N09925 Incoloy sawb lub zog siab, corrosion resistant hlau npib tsib xee:
1. Dab tsi yog qhov tseem ceeb ntawm N09925 Incoloy Sawb, thiab nws ua li cas thiaj pab nws ua tau zoo?
Teb:
N09925 Incoloy Sawb yog feem ntau tsim ntawm:
Nickel: kwv yees li 55-63%
Hlau: Tshuav (ncig 20-30%)
Chromium: 22-24%
Molybdenum: 3-5%
Tooj Liab: 0-1.5%
Titanium: kab nqis mus rau ruaj khov rau cov alloy ntawm qhov kub
Cov ntsiab lus ntawm Nickel muaj kev cuam tshuam zoo heev, thaum lub chromium thiab molybdenum kev ua kom zoo rau oxidation, pitting, thiab kev nyuaj siab corrosion tawg. Lub Molybdenum tseem muab lub zog ntxiv ntawm kev nce kub. Cov yam ntxwv no ua rau n09925 Incoloy qhov kev xaiv xaiv tau zoo tshaj plaws rau kev siv hauv kev mob hnyav.
2. Dab tsi kev lag luam siv N09925 Incoloy Sawb, thiab rau cov ntaub ntawv twg?
Teb:
N09925 Incoloy Sawb yog siv nyob rau hauv kev lag luam uas xav kom muaj zog thiab corrosion tsis kam, tshwj xeeb hauv qhov chaw siab. Kev Lag Luam Tib Neeg thiab Cov Ntawv Thov suav nrog:
Petrochemical Kev Lag Luam: Rau kev siv cov hauv cov khoom siv tau kub, xws li cov tshuaj tsuag reactor thiab kev hloov cua sov.
Tshuaj lom neeg: hauv cov pas dej piping, li qub, thiab cov khoom sib xyaw ua rau muaj kuab lom thiab roj.
Aerospace: Rau qhov kev kub ntxhov siab thiab cov kev ntxhov siab ntau xws li cov roj av tshuab thiab tso pa tawm.
Lub zog hluav taws xob: hauv kev hloov pauv cua sov thiab lwm yam kev kub siab thiab cov pa taws kub.
3. Dab tsi yog cov cuab yeej ua haujlwm ntawm n09925 Incoloy Sawb?
Teb:
N09925 Incoloy sawb muaj cov khoom siv zoo tshaj plaws, uas suav nrog:
Peple zog: kwv yees li 280 mpa (40,000 psi)
Lub zog tensile: ncig 700 MPa (100,000 psi)
Elongation: 40-50% hauv cov qauv
Hardness: Feem ntau 90 hrb (rockwell b nplai), nyob ntawm kev ua.
Cov khoom siv no muab N09925 Incoloy sawb lub zog kub, nrog rau kev ua kom zoo thiab ua kom haum, ua kom haum rau cov kev siv ua tau zoo hauv cov chaw muaj kev ua tau zoo.
4. N09925 Incoloy Sawb tawm tsam corrosion thiab oxidation?
Teb:
N09925 Incoloy Sawb cov ntsiab lus Nickel siab (nyob ib ncig ntawm 55-63%) ua rau nws corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv acidic thiab txo ib puag ncig. Lub alloy kuj muaj cov nyiaj ntau ntawm chromium, uas ua rau ib txheej oxide passive rau saum npoo av, tiv thaiv kev ua kom tsis txhob muaj oxidation ntxiv. Qhov sib ntxiv ntawm Molybdenum txhim kho kom pitting thiab crevice corrosion, thaum tooj liab muab kev tiv thaiv ntxiv tawm tsam cov kab mob uas muaj ib puag ncig. Cov Nta no tso cai n09925 los tswj nws txoj kev ncaj ncees txawm nyob rau hauv qhov hnyav, siab ib puag ncig ib puag ncig, xws li cov uas pom muaj cov nroj tsuag tshuaj thiab muaj cov roj.
5. Dab tsi yog cov txheej txheem fabrication yog rau n09925 Incoloy Sawb?
Teb:
N09925 Incoloy Sawb yog feem ntau tsim tau siv cov txheej txheem txias thiab cov txheej txheem kub kom ua cov tawv nyias nyias muaj tseeb nrog tuab thiab dav. Lub txheej txheem fab raug hluav taws xob muaj xws li:
Kub Rolling: los ua tus sawb puab thiab txo cov tuab ntawm cov alloy rau qhov loj me.
Colding colding: Kom ua tiav qhov kawg ntawm qhov kawg, txhim kho qhov chaw ua tiav, thiab txhim kho cov khoom siv tshuab los ntawm kev ua kom zoo cov qauv zeb.
Annealing: Kev kho cua sov yog ua los daws kev ntxhov siab thaum dov thiab txhawm rau txhim kho lub zog alloy lub zog thiab ductility.
Tom qab cov ntaub npog, cov kab txaij feem ntau siv hauv cov ntawv thov uas muaj peev xwm ua kom muaj zog ntxiv rau hauv cov roj gaskets, ntsaws ruaj ruaj, lossis cov tshuab ua kom sov, lossis ua kom sov lossis cua sov.
