Chromium yog tus thawj coj tus neeg sawv cev rau kev sib tham corrosion tsis kam nyob hauv nruab nrab nruab nrab lossis oxidizing ib puag ncig.
Nws tuaj yeem yooj yim welded thiab ua tiav los ntawm cov khw muag khoom siv cov kev coj noj coj ua.
316L, yog qhov kev xaiv zoo dua rau ib qhov project uas yuav tsum muaj ntau tus vuam vim 316 yog qhov ntxim nyiam ntau dua 316l (corrosion nyob rau hauv weld).
Qeb 304 Stainless hlau yog feem ntau suav hais tias yog feem ntau cov roj av tsis tshua muaj.
347 yeeb nkab thiab cov kua qaub rau cov kev ntsuas thiab kev txhim kho corrosion yog kev txhawj xeeb
Alloy 347h (untalial s3409) Phaj Stainless Hlau yog cov carbon ntau dua (0.04 ¨C 0.10) version ntawm alloy.
Qhov sib ntxiv ntawm tus qauv rau qib no muab nws zoo dua corrosion tsis kam tshaj li cov pa chromium-tsib xee stomfuric, phosphoric thiab acetic acids. Txawm li cas los xij, kev siv ntawm hydrochloric acid yog txwv.
347 Kev tiv thaiv zoo heev rau cov yeeb nkab nruab nrab
Cov ntsiab lus carbon tsawg ntawm Alloy 317L ua rau nws tau welded tsis muaj kev sib txuam corrosion los ntawm chromium carbide nag los nag kev ua kom nws siv nyob rau hauv cov xwm txheej zoo li-welded.
316 Muaj peev xwm qhia tawm kom tiv thaiv weld welk.
304 Stainless hlau tsis muaj ib qho tsis muaj zog: Nws yog kev ntxim rau corrosion los ntawm cov tshuaj chloride lossis cov dej qab ntsev xws li ntug dej hiav txwv.
Nws muaj qhov ua tau zoo heev rau intergranular corrosion tom qab kis tau kub hauv cov chromium carbide nag los nag (400 ¨c 816¡Ãc).?
Txog kev pab cuam uas yuav tsum tau siv tau zoo tshaj plaws thiab tawg khoom, incoloy 800h lossis 800 ht siv. Cov ntsiab lus siab ntawm npib tsib xee thiab chromium hauv cov alloys kuj muab cov tshuaj tiv thaiv corrosion.
304 Stainless hlau yog daim ntawv feem ntau ntawm cov hlau stainless hauv ntiaj teb vim nws zoo heev corrosion thiab tus nqi. Nws muaj 16% rau 24% chromium chromium thiab txog 35% npib tsib xee, ntxiv rau cov pa roj carbon thiab manganese.
316L kuj yog tus qauv zoo kawg rau kev kub siab, kev siv ntau xeb, uas yog vim li cas nws thiaj nrov rau kev siv hauv kev tsim kho thiab marine ua haujlwm.
904L Qib Stainless Hlau tsis zoo li lwm cov hlau. Vim nws cov roj, molybdenum, npib tsib xee thiab tooj liab, 904l steel nta mus rau corrosion, xeb thiab acids.
Alloy 904L Outperforms Lwm yam Austenitic stainless hlau vim muaj qib siab ntawm alloy thiab molybdenum.
316 Stainless hlau muaj ntau cov pa roj carbon ntau dua 316L. Qhov no yooj yim kom nco ntsoov, zoo li L sawv rau "tsawg."
Alloy 347 Stainless Hlau phaj ua yeeb yam zoo corrosion tsis kam uas yog piv rau 304.
Thaum xaiv cov hlau tsis xeb uas yuav tsum tau ua kom haum ib puag ncig, cov hlau tsis huv stainless hlau feem ntau siv.
Chromium, molybdenum thiab nitrogen nce kev tawm tsam rau pitting corrosion. Npib tsib xee ua cov qauv Austenic.
Lub alloy muaj cov oxidation zoo tsis kam thiab creep lub zog mus rau 1500¡Ãf (816¡Ãc). Nws kuj tseem muaj qhov ntsuas kub zoo tsawg.
Yeeb Nkab Tawv, Yeeb Nkab, Cov Piping System - Zhengzhou Huitong Pipeline Equipment Co., Ltd.
Cov hlau stainless 904l \ / 1.4539 cov khoom siv tau los ua cov khoom kub thiab cov hlau thiab cov khoom siv sib tw, nrog rau kev siv roj ntsha thiab welded
Alloy 347 (Unsen S34700) yog columbium stabilized ustenitic steelion steelion tsis kam thiab qee qhov zoo dua nyob rau hauv cov mob oxidizing zoo tshaj 321 (unc unical S32100).
Lub siab chromium cov ntsiab lus txhawb nqa thiab saib xyuas zaj duab xis passive uas tiv thaiv cov khoom hauv ntau qhov chaw muaj kev nyab xeeb.
Moly tsev neeg muaj peev xwm ua kom muaj peev xwm tiv thaiv kom kub thiab muaj lub zog muaj zog raws li kev mob siab.
316L yog qhov zoo heev li 316 hauv yuav luag txhua txoj kev.?
Cov nyiaj ntau ntawm cov npib tsib xee thiab chromium hauv cov hlau tsis muaj roj hauv Austenitic stainless cov khoom, raws li zoo heev corrosion tsis kam.
Ob lub cim tsis muaj stainless hlau feem ntau yog 304 thiab 316. Txhim kho qhov sib txawv ntawm cov neeg corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog ntau qhov ntsev lossis tshuaj chloride kis.
