1. Cov alloys muaj dab tsi, thiab lawv cov khoom tseem ceeb yog dab tsi?
Teb:
Cov khoom no suav nrog ntau yam nickel-raws li alloys:
Inconel 600 (UNS N06600 / ASTM B167): Zoo heev oxidation thiab corrosion kuj nyob rau hauv acidic thiab siab -kub ib puag ncig.
Inconel 625 (UNS N06625 / ASTM B444, B829): Siab tensile zog, creep kuj, thiab corrosion kuj, haum rau huab cua puag.
Inconel 601 (N06601): Tsim los rau siab -kub oxidation tsis kam, feem ntau siv rau hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
Tag nrho cov alloys no yog npib tsib xee-raws li, corrosion- tiv taus, thiab haum rau siab - kev siv kub, ua kom muaj kev ncaj ncees hauv kev ntxhov siab.
2. Dab tsi yog qhov tseem ceeb ntawm "seamless" rau cov nickel alloy raj?
Teb:
Seamless raj yog tsim tsis muaj welds, uas muab rau lawv:
Cov qauv kev ntseeg siab dua rau siab -siab thiab siab -kub siv
Zoo dua corrosion kuj vim tias tsis muaj vuam seams uas tuaj yeem ua raws li cov ntsiab lus tsis muaj zog
Precise dimension tolerances, zoo tagnrho rau cov khoom tseem ceeb hauv aerospace, tshuaj, thiab fais fab kev lag luam
Seamless kev tsim kho kom muaj kev ntseeg siab nyob rau hauv ib puag ncig huab.
3. Dab tsi yog cov kev siv ntawm cov nickel alloy raj?
Teb:
Cov raj no tau siv dav hauv kev lag luam uas xav tau siab -kub thiab corrosion- tiv taus kev ua haujlwm:
Aerospace: Gas turbine txias kab, tso pa tawm, thiab cov khoom siv cav
Tshuaj thiab petrochemical: Reactors, piping, thiab kub exchangers rau corrosive kua
Kev tsim hluav taws xob: Superheater tubing, boiler raj, thiab siab - kav dej kub
Marine thiab offshore: Piping raug dej hiav txwv thiab acidic tej yam kev mob
Kev sib xyaw ua ke ntawm lub zog siab thiab kev tiv thaiv corrosion ua rau lawv haum rau qhov chaw huab cua.
4. Cov raj nickel alloy ua li cas nyob rau hauv qhov kub thiab txias thiab corrosive tej yam kev mob?
Teb:
Inconel 600: tuav lub zog thiab corrosion kuj mus txog ~ 1093℃F (590 degree)
Inconel 625: Khaws lub zog tensile siab thiab nkag siab txog ~ 1800℃F (982 degree)
Inconel 601: Tsim los rau oxidation tsis kam ntawm qhov kub txog li 2000℃F (1093 degree)
Tag nrho cov alloys tiv thaiv oxidation, scaling, thiab corrosive nres, ua rau lawv txhim khu kev qha nyob rau hauv chemical, marine, thiab siab -kub siv.
5. Puas muaj kev txiav txim siab tshwj xeeb rau kev tsim, vuam, lossis tuav?
Teb:
Yog, nickel alloys yuav tsum tau ceev faj tuav vim hardness thiab corrosion kuj:
Machining: Yuav tsum muaj cov cuab yeej ntse carbide, coolant, thiab tswj cov khoom noj kom tsis txhob ua haujlwm hnyav
Vuam: Siv cov nickel{0}}raws li cov hlau; ib co alloys yuav tsum tau post-weld stress relief los tuav cov khoom siv kho tshuab
Kev tuav: Tsis txhob khawb los yog dents los tiv thaiv corrosion thiab qhov tseeb qhov tseeb
Kev tshuaj xyuas: Qhov tseem ceeb rau siab -kub lossis tshuaj siv tshuaj kom paub meej qhov ua tiav thiab phab ntsa thickness uniformity
