Yam khoom twg yog Incoloy 800?
Puas yog stainless hlau lossis nickel{0}}raws li alloy?
Incoloy 800 yog anickel-hlau-chromium austenitic tshav kub-resistant superalloy, thiab nws yog nruj me ntsis categorized li anickel{0}}raws li alloytsis yog stainless hlau.
Lub hauv paus kev faib tawm yog nyob rau hauv kev faib ua feem ntawm cov ntsiab lus alloying thiab nws cov kev taw qhia kev ua haujlwm. Los ntawm kev pom ntawm cov tshuaj muaj pes tsawg leeg, Incoloy 800 muaj30% - 35% npib tsib xee, 19% -23% chromium, thiab hlau yog cov khoom sib npaug, nrog cov kab ntxiv ntawm cov pa roj carbon, manganese, silicon, aluminium, titanium, thiab lwm yam. Nickel yog qhov tseem ceeb ntawm cov alloying uas txiav txim siab nws qhov kev ua tau zoo, uas yog qhov tseem ceeb rau kev txheeb xyuas cov nickel-raws li alloys. Los ntawm qhov sib piv, stainless hlau yog qhov tseem ceeb ntawm cov hlau-raws li alloy, nrog cov ntsiab lus chromium Ntau dua lossis sib npaug li 10.5% raws li cov ntsiab lus tseem ceeb kom ua tiav xeb, thiab nws cov ntsiab lus npib tsib xee feem ntau qis dua 20% (txawm tias siab -nickel austenitic stainless hlau, npib tsib xee tsuas yog ib qho ntxiv rau kev ua cov hlau tsis zoo).
Hais txog cov yam ntxwv ntawm kev ua tau zoo, cov ntsiab lus npib tsib xee ntawm Incoloy 800 muab nws zoo heev - qhov kub thiab txias stability, tsis kam mus rau intergranular corrosion, thiab oxidation tsis kam ntawm qhov kub siab (nws tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias mus txog 1100 degree). Cov khoom no yog qhov zoo tshaj plaws ntawm cov pa stainless hlau, uas yog tsim los rau corrosion kuj ntawm chav tsev kub los yog nruab nrab kub es tsis ntev - lub sij hawm kev pab cuam nyob rau hauv huab cua kub heev - kub.
Hauv cov ntawv thov kev lag luam, qhov kev faib tawm qhov sib txawv no kuj qhia txog nws cov xwm txheej: stainless hlau yog siv dav hauv cov khoom siv niaj hnub, kho kom zoo nkauj vaj tsev, thiab cov khoom siv tshuaj lom neeg; thaum Incoloy 800 yog tsom rau siab -kawg teb xws li petrochemical cracking furnaces, nuclear power steam generators, thermal power boiler superheaters, thiab aerospace engine Cheebtsam, qhov siab - kub thiab corrosion kuj yog qhov tseem ceeb.
