Nickel Alloy thiab Stainless HlauTaw qhia
Kev sib cav sib ceg ntawm nickel alloy thiab stainless hlau tau nyob ib puag ncig ntev thiab nws tseem txuas ntxiv mus. Ob qho khoom siv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo uas tuaj yeem ua rau nws nyuaj rau kev txiav txim siab seb qhov twg zoo dua. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov sib txawv ntawm cov nickel alloy thiab stainless hlau thiab pab koj txiav txim siab seb cov khoom twg yog qhov zoo rau koj daim ntawv thov.
Dab tsi yog nickel alloys thiab stainless hlau?
Nickel alloysyog cov alloys uas muaj nickel ua lub ntsiab. Lawv kuj muaj lwm yam khoom xws li tooj liab, chromium, molybdenum, thiab hlau. Nickel alloys paub txog lawv qhov zoo heev tiv thaiv corrosion thiab siab -kev siv kub. Lawv yog siv nyob rau hauv ntau yam kev siv xws li roj turbines, chemical processing, thiab aerospace.
Stainless hlau, ntawm qhov tod tes, yog ib qho alloy ntawm hlau, carbon, thiab lwm yam xws li chromium thiab npib tsib xee. Nws yog lub npe hu rau nws zoo heev corrosion kuj thiab lub zog. Stainless hlau yog siv nyob rau hauv ntau yam kev siv xws li cov khoom siv hauv chav ua noj, cov khoom siv tsheb, thiab cov khoom siv kho mob.

Cov qauv dawb tuaj yeem muab. Tiv tauj peb kom tau txais kev tsocai dawb.
Corrosion kuj
Ib qho tseem ceeb tshaj plaws los xav txog thaum xaiv cov nickel alloy thiab stainless hlau yog lawv cov corrosion kuj. Nickel alloys paub txog lawv qhov zoo heev tiv thaiv corrosion thiab tuaj yeem tiv taus qhov chaw hnyav xws li kub siab, acidic thiab alkaline daws, thiab dej hiav txwv. Lawv yog siv nyob rau hauv daim ntawv thov xws li tshuaj ua cov nroj tsuag, roj refineries, thiab lub zog tsim.
Stainless hlau kuj muaj kev tiv thaiv corrosion zoo heev thiab feem ntau siv nyob rau hauv ib puag ncig uas corrosion yog ib qho kev txhawj xeeb. Txawm li cas los xij, nws tsis tuaj yeem tiv taus corrosion li npib tsib xee alloys thiab tej zaum yuav corrode nyob rau hauv ib puag ncig xws li seawater thiab acidic daws.
Lub zog
Thaum nws los txog rau lub zog, ob qho tib sinickel alloy thiab stainless hlaumuaj lawv tus kheej zoo. Nickel alloys paub txog lawv lub zog siab thiab tuaj yeem tiv taus qhov kub thiab txias. Lawv feem ntau siv rau hauv daim ntawv thov xws li roj turbines thiab aircraft cav.
Stainless hlau tseem paub txog nws lub zog thiab kav ntev. Nws feem ntau siv rau hauv cov ntawv thov uas lub zog tseem ceeb xws li cov khoom siv tsheb thiab cov khoom siv kho mob.
Machineability
Lwm qhov yuav tsum tau xav txog thaum xaiv cov nickel alloy thiab stainless hlau yog lawv cov machinability. Nickel alloys tsis yooj yim rau tshuab li stainless hlau thiab xav tau cov cuab yeej tshwj xeeb thiab cov tswv yim. Lawv kuj nquag ua haujlwm hardening uas tuaj yeem ua rau lawv nyuaj rau tshuab.
Stainless hlau, ntawm qhov tod tes, yog yooj yim rau tshuab dua nickel alloys. Nws tuaj yeem ua tshuab siv cov txheej txheem machining thiab tsis xav tau cov cuab yeej tshwj xeeb lossis cov tswv yim.
Nqi
Tus nqi kuj yog ib qho tseem ceeb uas yuav tau xav txog thaum xaiv cov nickel alloy thiab stainless hlau. Nickel alloys feem ntau kim dua stainless hlau vim lawv cov ntsiab lus nickel siab. Txawm li cas los xij, lawv feem ntau tsim nyog rau kev nqis peev vim lawv cov kev tiv thaiv corrosion zoo heev thiab lub zog siab.
Stainless hlau feem ntau tsis tshua kim tshaj nickel alloys vim nws cov ntsiab lus qis nickel. Nws feem ntau yog tus nqi ntau dua - kev xaiv zoo rau cov ntawv thov uas qhov kev tiv thaiv corrosion tsis yog qhov kev txhawj xeeb loj.
Daim ntawv thov
Nickel alloys yog siv rau ntau yam kev siv xws li kev ua tshuaj lom neeg, tsim hluav taws xob, thiab aerospace. Lawv kuj tau siv nyob rau hauv marine ib puag ncig uas corrosion kuj yog ib qho kev txhawj xeeb loj.
Stainless hlau yog siv nyob rau hauv ntau yam kev siv xws li cov khoom siv hauv chav ua noj, cov khoom siv tsheb, thiab cov khoom siv kho mob. Nws kuj tseem siv rau hauv kev siv vaj tse vim nws qhov kev thov kom zoo nkauj.
Quality Assurance Testing Protocols
Tag nrho cov siab - cov khoom siv hauv cov kav dej yuav tsum dhau qhov kev kuaj xyuas pov thawj los tiv thaiv hauv - kev pabcuam tsis ua haujlwm. Thaum tshuaj xyuas cov ntaub ntawv ntsuam xyuas cov ntaub ntawv (MTRs), xyuas kom tiav ua raws li cov txheej txheem thoob ntiaj teb:
Khoom siv Standards:ASTM B167 / B444 rau seamless nickel alloy kav, ASTM B407 rau Incoloy, thiab ASTM A312 / A213 rau stainless hlau kav.
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):100% Ultrasonic Testing (UT) thiab Hydrostatic Pressure pov thawj los xyuas kom meej phab ntsa kev ncaj ncees nyob rau hauv kev ua hauj lwm loads.
Positive Material Identification (PMI):X-Ray fluorescence kuaj xyuas kom paub tseeb tias cov khoom sib xyaw ua ntej xa tawm.
