Kev Kawm Sib Piv: Haynes 230 vs Inconel 718 Alloy
Inconel 718 muaj qhov zoo heev - kub lub zog thiab corrosion kuj, ua rau nws zoo tagnrho rau kev thov xws li roj turbines thiab foob pob ua ntxaij cav; txawm li cas los xij, nws kim dua thiab nyuaj dua rau kev ua haujlwm. Haynes 230, ntawm qhov tod tes, ua tau zoo nyob rau hauv siab - qhov kub thiab txias ib puag ncig txog li 1400℃F (760 degree) vim nws lub zog zoo, oxidation tsis kam, thiab superior siab - kub ductility thiab creep resistance piv rau lwm yam alloys, ua rau nws haum rau lub cub tawg Cheebtsam thiab lwm yam muaj cua sov daim ntaub ntawv. Qhov kev xaiv ntawm ob feem ntau yog nyob ntawm qhov tshwj xeeb kub, lub zog, thiab tus nqi ntawm daim ntawv thov.
Dab tsi yog cov khoom ntawm Haynes 230 alloy?
HAYNES 230 (UNS N06230) alloy yog npib tsib xee -chromium-tungsten- molybdenum alloy uas ua ke zoo heev - kub lub zog, zoo heev corrosion kuj nyob rau hauv ntev - lub sij hawm raug oxidizing ib puag ncig mus txog 2100℃F (1) zoo heev tiv thaiv nitriding, thiab zoo heev ntev -lub sij hawm thermal stability.
Haynes 230

Daim ntaub ntawv: Gas turbine Cheebtsam, industrial furnace Cheebtsam, thiab cov khoom siv tshuaj.
Qhov tsis zoo: Nws qhov siab - qhov kub thiab txias yog qis dua Inconel 718.
ib 718
Qhov zoo: Zoo heev - qhov kub thiab txias zog thiab creep rupture zog txog li 1300℃F (700℃). Nws kuj muaj qhov zoo heev corrosion kuj.
Daim ntawv thov: Aerospace Cheebtsam, foob pob ua ntxaij cav, nuclear reactors, thiab lwm yam siab - kev nyuaj siab, siab - kev siv kub.
Disadvantages: Tus nqi siab dua, kev siv lub tshuab tsis zoo, thiab cov kev xav tau tshwj xeeb vuam ntau dua.
Kev sib piv ntawm cov tshuaj muaj pes tsawg leeg

Qhov tseem ceeb sib txawv thiab kev xav
Kub: Inconel 718 muaj qhov ua haujlwm kub ntau dua Haynes 230, tab sis Haynes 230 ua tau zoo nyob rau hauv 700-1400℃F (371-760 degree) ntau.
Corrosion Resistance: Inconel 718 pom zoo corrosion kuj.
Tus nqi thiab Machinability: Haynes 230 feem ntau yog kev lag luam thiab yooj yim dua rau tshuab dua Inconel 718, uas tuaj yeem kim heev thiab nyuaj rau tshuab.
Creep Resistance: Haynes 230 qhia txog kev nkag siab zoo, tshwj xeeb tshaj yog nyob rau hauv qis qis, thiab qee zaum, nws qhov kev tawm tsam ntawm qhov kub txog li 900℃yog superior rau lwm yam alloys. Inconel 718 kuj pom zoo heev creep rupture zog ntawm qhov kub txog li 1300℃F (700 degree).
Daim Ntawv Thov: Qhov kev xaiv zoo tshaj yog nyob ntawm daim ntawv thov tshwj xeeb qhov yuav tsum tau muaj qhov kub thiab txias, lub zog, thiab cov nqi txwv.
