Dab tsi yog qhov txawv ntawm inconel 750 thiab 718?
Inconel alloys paub txog lawv cov kev ua tau zoo hauv kev kub siab thiab kev ua kom haum. Ntawm cov nyiam tshaj plaws yog inconel 718 thiab Inconel x {1}}}}}} Nkag siab txog lawv qhov sib txawv, thiab cov ntawv thov tuaj yeem pab kev lag luam xaiv cov khoom zoo rau lawv cov kev xav tau.
Dab tsi yog inconel 718?
Inconel 718 bar, 718 inconel almoy bar
Inconel 718 yog npib tsib xee-raws li cov high-kub alloy paub rau nws lub zog siab, corrosion tsis kam, thiab zoo heev Veldability. Nws yog cov nag lossis daus hardenable, uas txhais tau hais tias nws cov khoom siv neeg tuaj yeem txhim kho los ntawm kev kho cua sov.
Ntau yam: ua tau zoo hauv qhov kub thiab txias nyob rau -250 degree rau 700 degree.
Corrosion Kuj: Zoo heev tiv taus rau oxidation, pitting, thiab kev nyuaj siab corrosion tawg txawm nyob hauv ib puag ncig hnyav.
Neeg kho tshuab zog: High tensile thiab tawm lub zog vim muaj ntawm niobium.
Cov ntawv thov: feem ntau yog siv hauv kev sib nqus tshuab, roj turbines, nuclear reactors, thiab roj thiab roj tawm.
Dab tsi yog inconel x -750?
Inconel x -750 yog lwm cov neeg npib tsib xee uas zoo li cov neeg muaj txuj ci siab. Nws tseem yog cov neeg mob siab, tab sis muaj ntau aluminium thiab titanium tshaj inconel 718, uas ua rau muaj peev xwm ua rau nws lub zog ntawm kev kub siab.
Ntau yam: kev ua tau zoo tshaj plaws txog 980 degree.
Cramp Kuj: Zoo heev tsis kam rau deformation raws li kev ntxhov siab ntev-kub ntxhov siab.
Corrosion Kuj: Zoo ua rau oxidation thiab tshuaj lom neeg corrosion, tab sis me ntsis tsawg dua li inconel 718.
Cov ntawv thov: feem ntau siv nyob rau hauv JET JURNAKES, nuclear reactors, springs, thiab fasteners.

Kev ua tau zoo hauv qhov chaw kub
Inconel 718:
Inconel 718 yog tsim rau nruab nrab rau cov ntawv thov kub siab, tab sis pib poob cov khoom siv puas tau tshaj 700 degree. Nws wardability ua rau nws tsim nyog rau kev tsim khoom uas yuav tsum muaj qhov tseeb.
Inconel x -750:
Inconel x -750 tuaj yeem tiv taus kub txog 980 degree thiab muaj cov creep kuj zoo heev. Qhov no ua rau nws haum ntau rau cov seem xws li turbine hniav thiab nuclear reactor springs uas yuav tsum tau nthuav tawm kom sov heev rau lub sijhawm ntev.
Inconel 718 vs inconel x {1}}}: uas yog qhov zoo dua?
| Kev ua | Inconel 718 | Inconel x -750 |
|---|---|---|
| Tus nqi | Tus nqi siab dua | Pheej yig dua |
| Luam ntawv | Yooj yim rau tshuab | Ntau nyuaj rau tshuab |
| Hwj txwv | Zoo tshaj | Tsawg weldable |
| Corrosion Kuj | Zoo tshaj | Tswj kav |
| Kub tiv thaiv | Txog 700 degree | Txog li 980 degree |
| Cov Ntawv Thov | High-zog, Corrosive Chaw | Kev kub-ib puag ncig |
Xaiv Inconel 718:
Yog tias koj daim ntawv thov yuav tsum muaj lub zog siab, txhim kho corrosion tsis kam, thiab kev ua tau kub ntxhov, xws li roj thiab roj av tsim khoom.
Xaiv Inconel X -750:
Yog tias koj daim ntawv thov cuam tshuam rau kev kub ntxhov thiab kev ntxhov siab ntev, xws li lub tshuab luam yeeb, xws li cov tshuab luam yeeb, lossis kub kub.
