** 1. Dab tsi yog qhov sib txawv ntawm 304L thiab 316L yeeb nkab? **
Qhov sib txawv ntawm kev sib txawv ntawm 304L thiab 316L stainless kav hlau yog lawv cov tshuaj lom neeg muaj tshuaj lom neeg (feem ntau 2 - 3%), thaum 304l muaj tsawg rau tsis muaj. Qhov no Molybdenum nthuav tawm kev txhim kho 316L kev tiv thaiv 316L kev tiv thaiv kom pittings, tshwj xeeb hauv cov ntaub ntawv ntawm ntug dej hiav txwv lossis hauv kev thov cuam tshuam nrog Saltwater, los yog txheej txheem tshuaj. Yog li ntawd, 316L yog qhov kev xaiv zoo dua rau kev ua kom haum corrosive, thaum 304l yog ib qho zoo tshaj plaws, siv lub hom phiaj zoo rau cov hlau tsis muaj zog.
** 2. Dab tsi yog l sawv rau hauv 304L stainless hlau? **
"L" sawv ntsug rau "cov pa roj carbon tsawg." Cov pa roj carbon cov ntsiab lus hauv 304L yog capped ntawm ntau tshaj plaws ntawm 0.03%, uas yog qis dua li 0.08% siab tshaj plaws hauv tus qauv 304 stainless hlau. Qhov no txo cov ntsiab lus carbon yog qhov tseem ceeb rau vuam. Nws minimization cov nag lossis daus ntawm cov chromium carbides hauv tshav kub "lossis" Weld tsis txaus ntseeg rau corrosion uas nyob ib sab ntawm Weld.
** 3. Dab tsi yog qhov txawv ntawm 316 thiab 316L? **
Qhov sib txawv ntawm 316 thiab 316L yog ib leeg cov ntsiab lus carbon. Tus Qauv 316 Stainless Hlau muaj qhov siab tshaj plaws cov ntsiab lus carbon ntau ntawm 0.08%, thaum 316L yog qhov qis dua ntawm cov pa roj hmab nrog ntau tshaj ntawm 0.03% carbon. Qhov no muab 316LIXI superSIFFICELS ZOO RAU SCRATITY (carbide nag lossis los nag) thaum vuam. Rau feem ntau cov ntawv thov, tshwj xeeb yog cov uas muaj kev tsim duab lossis raug rau kev ua kom haum ib puag ncig post {}} vuam, 316l yog cov khoom siv uas nyiam. Tus qauv 316 tej zaum muaj lub zog dua siab dua li cov neeg siv hluav taws xob ntau dua ntawm cov kev txiav txim siab tsis tshua muaj rau cov khoom siv feem ntau.
** 4. Muaj hnub nyoog 304 thiab 316 stainless yuav siv ua ke? **
Yog, 304 thiab 316 Stainless hlau feem ntau siv tau ua ke hauv ntau cov ntawv thov tsis muaj qhov tseem ceeb tshaj plaws hauv Galosion. Vim tias lawv yog ob qho tib si ustenitic stainless hlau uas zoo sib xws Electrochemical corrosion yog heev zog. Qhov tseem ceeb tshaj plaws yog ib puag ncig. Yog tias qhov ib puag ncig yog corrosive txaus rau kev tawm tsam 304, nws yuav tsim qhov teeb meem uas muaj peev xwm ua kom nrawm dua ntawm lub 304. Txawm li cas los xij, feem ntau cov kev pabcuam tshuaj lom neeg thiab kev siv tshuaj me me, siv ua ke tsis yog teeb meem.
** 5. Koj puas tuaj yeem siv WELD 304L rau 316L? **
Yog lawm, koj tuaj yeem ua tiav Weld 304L rau 316L. Lawv yog ob qho tib si Austenitic, tsawg- Cov hlau stainless hlau nrog Weldability zoo. Lawv cov tshuaj thiab cov kws kho tshuab zoo sib xws uas lawv suav hais tias yog kom muaj txiaj ntsig zoo rau txhua tus. Nws yog ib txwm xyaum los siv AWS ES309L (lossis ER309L) tub muab tub lim rau WELD no. Tus tub lim hlau no muaj cov ntsiab lus chromium ntau dua thiab muaj cov ntsiab lus ntawm ob lub hauv paus thiab ua kom pom tseeb lub suab, corrosion {} {tiv taus weld tso nyiaj.
