Nickel 200/201: Tensile zog ~ 380-550 MPa, yield zog ~ 60-350 MPa, elongation 30-50%.
3. Dab tsi yog cov ntawv thov siv rau cov nickel -raws li cov ntawv hlau thiab daim hlau?
Teb:
Monel 400 / K500: Cov khoom siv hauv hiav txwv, twj, li qub, cov tso tsheb hlau luam, cov kav dej hiav txwv.
Inconel 600/601: Rauv qhov chaw, tshav kub exchangers, chemical processing equipment.
Inconel 625: Gas turbines, tshuaj thiab petrochemical khoom, tshav kub exchangers, marine applications.
Inconel 718: Aerospace Cheebtsam, turbine discs, foob pob ua ntxaij cav, siab -kub yam ntxwv qhov chaw.
Nickel 200/201: Kev ua tshuaj lom neeg, cov khoom siv electroplating, cov hlab ntsha cryogenic, corrosion-cov ntawv resistant.
4. Cov ntawv, qhov ntau thiab tsawg, thiab thicknesses muaj rau cov ntawv thiab cov phaj no?
Teb:
Cov ntaub ntawv: Cov ntawv thiab daim hlau tuaj yeem muab kub- dov, txias- dov, lossis annealed nyob ntawm daim ntawv thov.
Thickness: Feem ntau ntawm 0.5 hli mus rau 200 hli rau daim ntawv thiab daim hlau.
Dimensions: Cov ntawv loj yog 1000 × 2000 mm, 1500 × 3000 mm, los yog kev cai ntau thiab tsawg ntawm kev thov.
Surface Finish: Mill tiav, polished, los yog txhuam nto muaj raws li qhov yuav tsum tau ua.
5. Yuav ua li cas cov nickel -raws li cov ntawv hlau thiab daim hlau yuav tsum tau tuav thiab khaws cia?
Teb:
Khaws rau hauv qhov chaw qhuav, qhov cua kom tiv thaiv oxidation saum npoo.
Tsis txhob sib cuag nrog cov ntaub ntawv abrasive lossis tshuaj corrosive thaum tuav.
Siv cov cuab yeej nqa kom zoo los tiv thaiv kev khoov lossis khawb, tshwj xeeb tshaj yog rau cov ntawv nyias nyias.
Ntxuav nrog cov uas tsis yog- abrasive, me ntsis daws yog tias xav tau ua ntej fabrication.
Kev tshuaj xyuas ib ntus rau saum npoo corrosion los yog tsis xws luag, tshwj xeeb tshaj yog nyob rau hauv marine los yog tshuaj ib puag ncig.
