Stainless hlau kav yog dav siv hauv ntau qhov kev lag luam vim lawv cov kev ua tau zoo corrosion, siab zog, thiab kev pom zoo. Ntawm no yog hom hom hom.
Cov Hom Feem Ntawm Cov Kav Hlau Stainless Hlau
1.What yog Austenitic stainless hlau yeeb nkab?
Kev sib xyaw cov yam ntxwv: Feem ntau yuav muaj chromium (CR, feem ntau yog 184,5% (Si)
Cov yam ntxwv ua tau: Muaj cov khoom ua tau zoo corrosion, muaj peev xwm tiv taus cov organic accic, thiab cov ntsev inorganic rau hauv huab cua thiab cov xov xwm tsis muaj zog. Nws tseem muaj kev muaj zog zoo thiab weldability, nrog rau kev ua kom zoo ntawm cov kub tsawg. Txawm li cas los xij, nws lub zog yog tsawg tsawg ntawm cov hlau hlau tsis muaj zog, thiab nws tsis muaj hlau nplaum (lossis tsis muaj zog sib nqus tom qab ua haujlwm txias).
Cov qib kawm: 304, 304L (cov khoom siv roj carbon tsawg), 316, 311 (ntxiv rau Titanium (TI) txhawm rau txhim kho kev txhim kho corrosion), thiab lwm yam.
2.What yog ferritic stainless hlau yeeb nkab hlau?
Kev sib xyaw cov yam ntxwv: Chromium cov ntsiab lus yog tus muaj siab (feem ntau 12-30%), muaj cov pa roj carbon monoman, thiab nws feem ntau tsis muaj cov kab tsib, xws li 430 stainless hlau yeeb nkab hlau.
Cov yam ntxwv ua tau: Zoo corrosion tsis kam nyob rau hauv oxidizing media, xws li atmospheric corrosion. Nws muaj qee yam muaj zog thiab coj kev tiv thaiv thiab sib nqus. Txawm li cas los xij, nws cov formability thiab weldability yog neeg txom nyem tshaj li Austenitic Stainless hlau, thiab nws qhov qis-kub yog qis dua.
Cov qib kawm: 430, 409 (siv nyob rau hauv cov tshuab ntsuas tsheb, nrog cov oxidation siab tiv thaiv), thiab lwm yam.
3.Qhov Martensitic Stainless Hlau?
Kev sib xyaw cov yam ntxwv: Chromium cov ntsiab lus feem ntau yog 11.5-18%, xws li 410 cov yeeb nkab steel hlau.
Cov yam ntxwv ua tau: Tom qab kev kho cua sov (quenching + tempering), nws muaj lub zog siab, tab sis nws cov hom mob corrosion, tab sis nws cov hom stainless hlau, thiab nws sib nqus.
Qeb: 410, 420, 440 (ntau dua cov ntsiab lus carbon), siv ntau dua, siv rau cov cuab yeej thiab hnav-resistant seem).
4.What yog duplex cov yeeb nkab steel hlau?
Kev sib xyaw cov yam ntxwv: Kev sib xyaw ua ke ntawm cov hlau ua ke thiab cov ntsiab lus chromium feem ntau 21-28%, thiab cov ntsiab lus xws li molybdenum thiab nitrogen (n). Tus sawv cev raug cai yog 2205 duplex stainless hlau yeeb nkab hlau.
Cov yam ntxwv ua tau: sib xyaw ua ke ntawm ob qho tib si ntawm cov hlau tsis muaj zog (muaj zog tshaj plaws (zoo dua li cov tshuaj tiv thaiv corroside zoo tshaj plaws (siab tshaj plaws kev nyuaj siab corrosion), thiab kev nyuaj siab tsim kho corrosion), thiab kev nyuaj siab tsim kho corrosion), thiab zoo weldability thiab weldability zoo thiab firdability thiab firmability.
Cov qib kawm: 2205, 2507 (ntau lub zog thiab corrosion tsis kam, siv nyob rau hauv ib puag ncig ib puag ncig zoo li ntug dej platform).
