ASTM A182 F304 stainless hlau flanges yog tsim tau raws li Asme B16.5 150 #, 600 #, 900 #, 2500 #.

Nrog qhov no zoo yaj taw tes, cov flange tuaj yeem tiv taus kub txog 870 degrees Celsius. Muaj ntau hom flanges raws li hom ntsej muag. 304 Stainless hlau flanges yog muaj nrog tiaj tus, tsa thiab ntiv nplhaib pob qij txha.

Ib qho kev siv tshuaj tsis huv stainless hlau, tshuaj lom neeg muaj pes tsawg leeg ntawm stainless hlau 304 flanges muab nws kom zoo dua cov roj carbon steel. Txawm hais tias lawv raug nqi ntau dua yav dhau los alloys, kev ua haujlwm uas lawv muab siv daim ntawv thov mus rau qib tom ntej.

Hauv kev lag luam uas tuav nitric acid, qib 304 stainless hlau xov flanges tuaj yeem siv nyob rau ntawm kub txog li 176¡Ãf. 304 Stainless hlau flanges yog ruaj thiab tsis kim tsawg dua li lwm cov alloy hom. Vim yog cov oxidizing cov yam ntxwv ntawm cov tshuaj no, nws yuav nrawm nrawm yog siv cov kev ua kom muaj 55%.

Lwm txoj kev lag luam uas siv cov alloy yog cov zaub mov thiab dej haus kev lag luam, uas siv acetic acid raws li cov tshuaj tiv thaiv. Acetic acid yog ib organic acid uas yog corrosive rau cov roj carbon hlau.

Cov ntsiab lus npib tsib xee nyob rau hauv stainless hlau unsed s9400 dig muag flanges tiv thaiv cov khoom siv xeb, suav nrog acetic acid thiab phosphoric acid, uas yog ib qho acid.

Lub pas dej stainless 304 flange ua rau nws yooj yim rau siv cov tshuab uas yuav tsum tau vuam.

Hom 316 stainless hlau yog tsim mus rau lwm qib vim nws cov peev xwm ntau ntawm cov peev xwm thiab yog txawv los ntawm kev siv tsab ntawv "l" hauv nws lub npe. L sawv cev cov ntsiab lus muaj roj carbon tsawg hauv cov hlau.

316L yog cov paub zoo tshaj plaws ntawm cov tuam ntxhab rau kev tawg ua tom qab cov txheej txheem vuam tiav. Qhov no ua rau 316L thawj qhov kev xaiv rau cov tuam ntxhab tab tom tsim tsa cov qauv hlau rau kev siv cov ntawv thov.

Dhau li ntawm L, muaj lwm cov lus qhia me me xws li F, N, H thiab ntau lwm tus, ntawm cov roj ntsha, npib chromenum, thiab lwm yam kom tau txais cov khoom xav tau.

Cov ntawv thov raug rau cov khoom lag luam muaj xws li: Khoom noj khoom noj, kuaj cov tshuaj sib txuas, cov ntxaij ntim, cov ntxaij vab tshaus, cov tsheb ciav hlau, cov tub rog ua si, chaw ua haujlwm ntawm dej thiab dej hiav txwv. Ib qho ntawm cov qauv tseem ceeb ntawm 316L Stainless hlau thiab 316 Stainless hlau yog tias cov ntsiab lus carbon ntawm lub tom kawg yog siab li 0.08%. Cov kev sib txawv no muab cov khoom sib txawv. Cia peb kawm paub ntxiv txog 316L stainless hlau alloy.

Qhov twg yuav tsum muaj vuam yuav tsum tau, cov hlau muaj cov cuab yeej ntawm kev tawg vim tias nws txias. Qhov kub ntawm cov txheej txheem vuam ua rau paub dab tsi yog hu ua "kub embrittlement" raws li cov hlau txias. Qhov no ua rau cov qauv tsim muaj nrog cov ntsiab lus muaj roj carbon ntau dua vim kev tsim cov kab nrib pleb hauv cov chaw uas hlau yog welded. 316L stainless hlau alloy yog siv nyob rau hauv ntau cov ntawv thov raws li nws yog zoo haum kom tsis txhob muaj weld corrosion. Nws tseem tuaj yeem tiv thaiv kom kub thiab muaj lub siab tau zoo nyob rau ntawm 2,500 degrees Fahrenheit lossis txog 1,370 degrees Celsius. Ntxiv rau cov pa roj carbon, cov alloy muaj txog li 2% manganese thiab nce mus txog 0.75% silicon.

Cov khoom siv roj carbon qis ntawm 316L muab cov tshuaj zoo rau cov teeb meem engineering nrog 316 stainless hlau. Qhov kev hloov pauv me me no hauv koj daim ntawv thov tuaj yeem cuam tshuam loj rau koj cov nqi kev ua haujlwm thiab kev ntseeg zoo ua lub koom haum ua lag luam. Tsis zoo li lwm hom hlau xws li 304 thiab 306, lub 316L Stainless hlau Alloy tuaj yeem siv ntau yam kev siv rau qhov twg siab corrosion yuav tsum muaj. Piv txwv li, cov kws tshaj lij hauv cov tshuaj thiab cov tshuaj lag luam siv nws ua rau kev phais cov cuab yeej thiab kev cog phom.

Vim hais tias lub alloy yog ib qho yooj yim los ua haujlwm nrog thiab tsis tshua muaj kev puas tsuaj, cov tuam txhab khoov nws mus rau hauv ntau cov duab thiab cov ntaub ntawv. Piv txwv li, 316L stainless hlau muaj nyob rau hauv sawb, hlau, ntawv, bar thiab lwm yam duab. Txhua txoj kev lag luam tau ua tiav cov hlau no los tsim ntau yam cov khoom tiav.

Txawm hais tias ob qho ntawm cov hlau no tau txiav txim siab cov roj carbon hlau tsawg, lawv sib txawv heev. Piv txwv li, "l" sawv ntsug rau "tsawg" hauv 316L stainless hlau, lub ntsiab lus lub alloy muaj cov ntsiab lus muaj roj carbon tsawg heev. Lub 316L variant kuj tseem tiv taus solder corrosion thiab tuaj yeem tiv thaiv kom ntau dua li 316. Qhov no yog siv hauv marine thiab cov phiaj xwm kos duab.
