Nws ncav cuag cov theem sib npaug ntawm Austenite thiab ferrite nyob rau hauv ntxhib ib yam ntim ntim.

Cov txiaj ntsig lub zog tseem siab dua, pub cov tsim qauv sib xyaw los txo cov ntawv thov thauj khoom.

Qhov no alloy tiv taus chloride ib puag ncig thiab sulfide kev nyuaj siab corrosion. Nws tseem yog kwv yees ob npaug lub zog ntawm cov qauv ntawm cov hlau tsis huv.

ASTM A182 F51 ENESTENTED TSIS TXAUS SIAB RAU S31803. Qhov no yog thawj lub caption rau 22% crulex stainless hlau.

Cov qib kawm no, nrog kev qhia nrawm nrawm dua, yog cov ntawv sau ua ke raws li F60, sib npaug rau Unru S32205. Thiaj li, S32205 tuaj yeem ua tiav daim ntawv pov thawj raws li S31803 tab sis tsis yog lwm tus.

Duplex stainless hlau yog tsim los ua ke kom txhim kho kev ua kom haum corrosion (suav nrog sulfide corrosion thiab siab zog thaum piv nrog lwm cov khoom stainless.

Duplex stainless yog sib xyaw microstructure ntawm Austeniture ntawm Austeniture ntawm Austenitic thiab Ferrite (50) uas tau txhim kho cov hlau qib siab nrog corrosion tsis kam.

S31803 tau muab ntxiv los ntawm S32205 (F60) uas muaj qhov tsawg dua n, mo, ni thiab cr xij uas lav tau corrosion zoo dua.

Nws suav rau ib puag ncig 80% ntawm tag nrho cov duplex stainless ntau lawm.

Nrog rau cov ntsiab lus chromium nce ntxiv piv nrog F51 nws muaj kev txhim kho pitit corrosion.

Uns31803 tau muab ntxiv los ntawm s32203 (F60)

S31803 tau muab ntxiv los ntawm S32205 (F60) uas muaj qhov tsawg dua NI CR thiab MO.

S31803 tau muab tso ntxiv los ntawm S32205 uas muaj qhov tsawg dua N, CR thiab MO.

Nws tseem zoo tagnrho rau kev lag luam rhiab xws li kev npaj khoom noj thiab khoom noj, uas muaj kev pheej hmoo ntawm kev paug qis dua.

Txawm hais tias 316L muaj tsawg dua carbon, 316 thiab 316L stainless hlau tau nqi kwv yees li tib yam.

316L stainless hlau muaj tsawg dua carbon thiab molybdenum dua li raug 316 hlau, uas muab ob alloys sib txawv.

Stainless hlau yog qhov zoo tagnrho rau cov ntawv thov ntev lub sijhawm uas yuav ntsib cov ntsiab, noo noo, thiab cov peev xwm tshuaj corrosive.

316L cov hlau yog cov ntau tau ua rau muaj qee qib ntawm Magnetism.

316L yog qhov kev xaiv zoo dua rau cov kev siv kub thiab ntsuas kub. Txij li 316L muaj tsawg dua carbon ntau dua 316, nws tau zoo dua intergranular corrosion tsis kam, txhais tau tias nws cov vev yeejït lwj, tsis zoo li nrog 316 stainless hlau.

Txhawm rau tsim nyog li 316L stainless hlau, tus nqi ntawm cov pa roj carbon ua tsis tau dhau 0.03%. Qhov no txo ​​qis kev pheej hmoo ntawm cov pa roj carbon daus, ua rau nws xaiv tau zoo dua rau kev siv vuam kom ntseeg tau ntau rau corrosion siab tshaj plaws.

Tus qauv Austenitic kuj tseem muab cov qhab nia cov qhab nia no ua tau zoo heev, txawm tias qhov kub tau txias.

Stainless hlau kuj yog tsim ntawm tsawg kawg 10.5% chromium, lub teeb ci uas muab cov hlau nws ua tiav thiab zoo dua corrosion tsis kam.

Qeb 316L, cov pa roj carbon tsawg ntawm 316 thiab yog tiv thaiv tau los ntawm kev nkag siab (Lis Ciam Cuam Tshuam Carbide nag lossis daus).

316L muaj qhov feem ntau ntawm cov pa roj carbon rau hauv nws txoj kev sib xyaw.

Piv rau chromium-npib tsib xee ustenitic stainless hlau muaj siab dua, kev ntxhov siab rau lub zog sib xyaw thiab tensile muaj zog ntawm cov kub.

Hom 316L stainless hlau nyob rau hauv molybdenum cov kabmob ustenitic.

Nws yog qhov dav dav hauv kev ntsuas hnyav welded Cheebtsam (dhau li ntawm 6 hli). Muaj feem ntau tsis muaj tus nqi pheej sib txawv ntawm 316 thiab 316L stainless hlau.

Nws yog cov tiv taus dav dav rau kev corrosion thiab pitting tshaj li cov pa nickel chromium chromium stainless hlau xws li 302-304.

316L yog nrov rau cov tshuaj thiab cov cuab yeej thaij duab vim tias nws tuaj yeem tiv taus vuam thiab cov tshuaj corrosive.

Peb muab cov ansi b16.5 phaj flanges rau kev lag luam irration.
