1. Inconel 718 (UNS N07718, W. Nr. 2.4668) yog dab tsi thiab nws cov yam ntxwv tseem ceeb?
Teb:
Inconel 718 (UNS N07718, W. Nr. 2.4668) yog lub siab -lub zog, corrosion{5}}resistant, nickel-raws li superalloy. Nws yog tsim los rau siab - daim ntawv thov kub, nrog zoo heev tiv thaiv oxidation, carburization, thiab thermal creep. Inconel 718 khaws nws cov khoom siv kho tshuab txawm tias qhov kub txog li 700℃(1,300℃F), ua rau nws haum rau aerospace, turbine, thiab lwm yam siab -kev ua haujlwm. Nws lub zog siab ntawm qhov kub siab, ua ke nrog kev sib txuas zoo, ua rau nws yog qhov kev xaiv nrov rau cov khoom tseem ceeb.
2. Dab tsi yog cov ntawv thov ntawm Inconel 718 round bars?
Teb:
Inconel 718 round bars feem ntau siv nyob rau hauv siab - kev ntxhov siab, siab - qhov kub thiab txias. Qee cov ntawv thov raug suav nrog:
Turbine hniav thiab rotors hauv dav hlau thiab roj turbines
Rocket engine Cheebtsam
High -kev ua tau zoo lub cav qhov chaw
Kub exchangers
Cov cuab yeej siv tshuaj
Nuclear reactors
Cov Cheebtsam no xav tau cov cuab yeej tshwj xeeb tshwj xeeb thiab siab -kev ua haujlwm kub uas Inconel 718 muab.
3. Dab tsi yog cov yam ntxwv tseem ceeb ntawm Inconel 718 uas ua rau nws haum rau siab -kev siv kub?
Teb:
Inconel 718 yog tshwj xeeb tshaj yog paub rau nws cov khoom zoo heev nyob rau hauv siab -kub ib puag ncig:
Siab zog thiab hardness ntawm siab kub
Oxidation thiab corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv siab -kub roj thiab kua ib puag ncig
Zoo weldability, uas ua rau nws yooj yim rau txheej txheem thiab tsim rau hauv cov khoom
Creep thiab qaug zog tiv thaiv nyob rau hauv qhov kub thiab txias
Cov khoom no tso cai rau Inconel 718 ua haujlwm nyob rau hauv qhov xwm txheej hnyav uas lwm cov ntaub ntawv yuav ua tsis tiav.
4. Dab tsi yog cov cuab yeej cuab tam ntawm Inconel 718 round bars?
Teb:
Inconel 718 round tuav muaj cov khoom zoo heev, suav nrog:
Tensile Strength: Feem ntau mus txog 1,270 MPa (185,000 psi) ntawm chav tsev kub
Tawm Zog: Nyob ib ncig ntawm 1,100 MPa (160,000 psi)
Elongation: Kwv yees li 20-25% ntawm chav tsev kub
Hardness: Ntawm 35-42 HRC (Rockwell C nplai)
Cov txiaj ntsig no ua rau Inconel 718 puag ncig cov kab muaj kev ntseeg siab rau cov khoom raug rau cov neeg kho tshuab siab thiab kub siab.
5. Inconel 718 ua haujlwm li cas ntawm kev tiv thaiv corrosion?
Teb:
Inconel 718 nthuav tawm qhov ua tau zoo rau ob qho tib si oxidation thiab corrosion nyob rau hauv siab - qhov kub thiab txias. Nws yog resistant rau:
Oxidation nyob rau hauv ob qho tib si huab cua thiab siab - kub gases txog li 1,000℃(1,832℃F)
Sulfur-induced corrosion, uas yog ib qho tseem ceeb tshwj xeeb hauv cov roj turbines thiab lwm yam combustion-txog daim ntawv thov
Pitting thiab crevice corrosion, uas ua rau nws haum rau siv nyob rau hauv hnyav tshuaj ua ib puag ncig
Qhov tshwj xeeb corrosion kuj yog ib qho ntawm cov laj thawj tseem ceeb vim li cas Inconel 718 tau siv dav hauv kev lag luam xws li aerospace, nuclear, thiab kev ua tshuaj lom neeg.
