Cov qib no ntawm cov hlau tsis huv no yog qhov ntau tshaj plaws thiab siv cov yeeb nkab ntau tshaj 304 thiab 304l stainless hlau yeeb nkab muaj peev xwm ua tau zoo thiab chaw hnyav.
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.
ASTM A240 yog cov txheej txheem kev qhia tshwj xeeb rau chromium thiab chromium-npib tsib xee stainless hlau phaj, ntawv, thiab sawb rau cov ntawv thov siab thiab rau cov ntawv thov siab.
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.
Lub alloy tau pom zoo heev rau intergranular corrosion nyob rau hauv cov as-welded mob.
Stainless Hlau Yeeb Nkab 18 40s ASME B36.19, Astm A312 Qib TPA004L, ERW 100% RT, L = 11.8MPC
347 Raug tshem tawm rau qhov kub hauv cov chromium carbide nag lossis daus cov kab mob
Stainless hlau 304 daim ntawv yog ua los ntawm Austenitic Stainless hlau uas muaj 18% chromium thiab 8% npib tsib xee nyob rau hauv cov muaj pes tsawg leeg.
Alloy 904L Outperforms Lwm yam Austenitic stainless hlau vim muaj qib siab ntawm alloy thiab molybdenum.
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.
304,304L, 304H, 309h, 310H, 310H, 316,34L, 311,34sh, 904sh, 904sh, 904Smo, Al6KHou 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
Qib 904L tsis tshua muaj kev tiv taus rau nitric acid dua qib 304L thiab 310L, uas yog cov molybdenum. Cov qib hlau no yuav tsum tau kho cov tshuaj no tom qab ua haujlwm txias, kom ua tiav kev ntxhov siab tshaj plaws ua rau muaj kev cuam tshuam hauv ib puag ncig
Lawv pom tias muaj kev tiv thaiv corrosion zoo heev rau ntau qhov kev xeb ib puag ncig. Hom 304 thiab 304L cov qib ntawm cov hlau tsis muaj peev xwm zoo machines.Qhov khoom siv tau zoo heev thiab siv tau ntau yam kev siv thiab kev lag luam.
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.
ASTM A860 Why 52 Fittings tau ua los ntawm cov roj carbon ntau, tus tub rog, tooj, lub nroog tooj liab, cov roj ntsha li ntawm A860 Whbake yog ib qho kev daws teeb meem.
ASTM A234 WP9 Cov Yeeb Nkab Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob txhais tau tias cov khoom siv kub siab.Qhov kev pab cuam lub siab. Cov khoom lag luam muaj ntau yam vim tias muaj ntau yam zoo tshaj plaws uas nws muaj.
Stainless hlau yog ib qho alloy ntawm cov hlau uas tiv taus xeb. Nws muaj tsawg kawg yog 11% chromium thiab tej zaum yuav muaj cov ntsiab lus xws li carbon, lwm yam tsis yog lwm yam kom tau lwm yam uas xav tau. Stainless hlau qhov tsis kam rau corrosion tau los ntawm cov chromium, uas ua cov yeeb yaj kiab passive uas tuaj yeem tiv thaiv cov khoom thiab kho tus kheej nyob rau hauv lub xub ntiag ntawm oxygen.Lub tshuab hluav taws xob stainless hlau yog cov khoom ntawm kev xaiv rau nqa cov tshuaj corrosive lossis cov roj av, tshwj xeeb yog qhov kev ntsuas siab, siab dua ib puag ncig muaj kev koom tes. Raws li qhov tshwm sim ntawm kev ua kom zoo nkauj ntawm cov hlau stainless, cov yeeb nkab feem ntau siv hauv cov ntawv thov archectural.
