1. Yuav ua li cas zoo Inconel 625, 600, 601, 800/800H, 718, 725, 926, thiab X-750 raj muab piv nrog stainless hlau?
Teb:
Nickel-raws li alloys muab kev ua tau zoo tshaj li cov qauv stainless hlau, suav nrog:
Superior siab -kub lub zog mus txog 1000-1200℃(nyob ntawm qib)
Exceptional tsis kam rau oxidation, carburization, thiab nitriding
Zoo corrosion kuj nyob rau hauv acids, seawater, thiab chloride ib puag ncig
Lub neej ua haujlwm ntev nyob rau hauv huab cua kub thiab tshuaj lom neeg
Kev qaug zog ntau dua, nkag mus, thiab kev ntxhov siab- tawg lub zog
Cov txiaj ntsig zoo no ua rau cov nickel alloys nyiam xaiv rau qhov chaw hnyav uas cov hlau tsis muaj hlau yuav ua tsis tiav.
2. Vim li cas cov Inconel thiab npib tsib xee - cov qib alloy feem ntau siv rau electroplating thiab Ni- cov khoom tsim khoom?
Teb:
Nickel alloys xws li Inconel 600/601/625 thiab 800H nthuav tawm:
Zoo heev stability nyob rau hauv acidic thiab alkaline plating da dej
Tsawg kis kab mob thiab cov khoom siv tsawg tsawg
High purity thiab tsis kam rau hlau ion leaching
Muaj peev xwm tiv taus thermal cycling tsis tu ncua hauv plating systems
Qhov no ua kom zoo ib yam plating zoo thiab txo qis sijhawm rau kev saib xyuas thiab hloov cov kav dej thiab cov khoom siv cua sov.
3. Dab tsi yog cov ntawv thov kev lag luam rau Inconel 718, 725, 926, thiab X-750 raj / kav?
Teb:
Cov high -kev ua tau zoo alloys yog dav siv nyob rau hauv:
Aerospace: turbine engines, tso pa system, afterburners
Roj & roj: downhole tubing, qaub-gas kev pab cuam, siab- qhov dej siab
Thaum tshav kub kub- kho cua sov: fixtures, radiant tubes, txhawb cov hlab
Kev siv tshuaj: reactors, kub exchangers, acid tuav
Kev tsim hluav taws xob: superheater tubes, siab -kub chav tshuab
Marine & seawater systems: desalination, twj tso kua mis, cua sov-exchanger tubing
Txhua qib alloy raug xaiv raws li qhov kub thiab txias, hom corrosion, thiab mechanical load.
4. Kev tshuaj xyuas thiab kev sim ua dab tsi ua ntej xa khoom mus rau lub Hoobkas - ncaj qha nickel alloy raj / yeeb nkab?
Teb:
Yuav kom ntseeg tau zoo, manufacturers feem ntau ua:
100% PMI (Positive Material Identification)
Hydrostatic los yog pneumatic siab kuaj
Eddy-tam sim no lossis ultrasonic NDT rau phab ntsa tuab thiab qhov tsis xws luag
Mechanical tests - tensile, yield zog, elongation, hardness
Grain loj thiab microstructure tsom xam
Dimensional raug kuaj - OD, phab ntsa thickness, ncaj, nto tiav
Kev ntsuam xyuas yog ua raws li ASTM B163, B167, B444, B622, B423, B751, lossis cov neeg siv khoom- cov qauv qhia.
5. Cov neeg siv khoom yuav tsum xav txog dab tsi thaum xaiv qhov raug nickel alloy qib rau lawv daim ntawv thov?
Teb:
Cov kev xaiv tseem ceeb suav nrog:
Ua haujlwm kub (600 vs 800 vs 1100℃ib puag ncig)
Corrosion media (chlorides, sulfur compounds, acids, oxidizing gases)
Mechanical xav tau (yield zog, qaug zog kuj, creep stability)
Weldability thiab fabrication xav tau
Cov qauv siv tau: ASTM / ASME, NACE MR0175 / ISO15156 rau roj & roj
Tus nqi -kev ua tau zoo piv
Piv txwv li, Inconel 625 yog zoo tagnrho rau seawater thiab tshuaj nroj tsuag,
Inconel 718/725 rau siab zog hauv aerospace thiab roj qhov dej,
Incoloy 800H rau siab -kub oxidation, thiab
X-750 rau cov springs thiab high-stress Cheebtsam raug tshav kub.
