Tso lus
Dab tsi yog qhov sib npaug ntawm 3CR12 stainless hlau?
3CR12 feem ntau sib npaug rau European qib 1.4003 (X2CrNi12) thiab Asmeskas kev xaiv UNS S41003 (lossis qee zaum S40977). Nws yog 12% chromium ferritic stainless hlau nquag siv los ua tus nqi -zoo, corrosion{10}} tiv taus lwm txoj rau cov qauv carbon steels.
Qhov sib npaug ntawm SS 304 yog dab tsi?
Thawj qhov sib npaug ntawm SS 304 (UNS S30400) yog EN 1.4301 (X5CrNi18-10). Lwm qhov sib npaug thoob ntiaj teb suav nrog Japanese JIS SUS 304, Swedish SS 2332, thiab nws feem ntau hu ua 18/8 stainless hlau vim nws muaj pes tsawg leeg ntawm roughly 18% chromium thiab 8% npib tsib xee.

3CR12 Stainless Hlau vs . 304: Corrosion Resistance
304 stainless hlau muaj superior, siab - qib corrosion kuj rau kev siv dav dav, kho kom zoo nkauj, thiab huv si. 3CR12 yog tus nqi qis dua, muaj "utility" ferritic stainless hlau tsim rau cov chaw ntub dej ntub. Thaum 3CR12 muaj kev tiv thaiv corrosion zoo dua li cov hlau me me, nws yooj yim rau xeb thiab qis dua rau 304 hauv ib puag ncig hnyav.
Koj puas tuaj yeem txuas 3CR12 rau cov hlau me me?
Lawv tuaj yeem raug welded rau lwm cov hlau ferrous, piv txwv li me me thiab stainless hlau, txaus siab heev. Cov qib pom zoo ntawm electrode yog 309L. Thaum vuam cov khoom siv hluav taws xob ferritic rau nws tus kheej, E308L lossis E316L tuaj yeem siv tau.
Puas yog 3CR12 stainless hlau hlau nplaum?
Yog lawm, 3CR12 stainless hlau yog hlau nplaum. Raws li cov khoom siv hluav taws xob ferritic stainless hlau (feem ntau hu ua 1.4003 lossis 12% chromium steel), nws muaj lub cev -centered cubic crystal qauv, uas ua rau nws muaj zog txaus nyiam cov hlau nplaum.
Puas yog 3CR12 stainless hlau xeb?
Yog lawm, 3CR12 stainless hlau tuaj yeem txhim kho qhov xeb lossis tshuaj yej-staining thaum raug hnyav lossis corrosive cua, vim nws yog tsim los rau kev siv hluav taws xob ntau dua li kev zoo nkauj, corrosion- dawb kev zoo nkauj. Raws li cov khoom siv hluav taws xob ferritic stainless hlau (12% chromium), nws muaj kev ua haujlwm zoo tshaj cov pa roj carbon steel tab sis tsis yog corrosion- pov thawj, feem ntau siv qhov chaw staining yog siv tau lossis hauv cov ntawv pleev xim.
Qhov txawv ntawm 3CR12 thiab 316 yog dab tsi?
3CR12 thiab 316 sib txawv feem ntau nyob rau hauv corrosion kuj, muaj pes tsawg leeg, thiab nqi . 316 yog ib tug siab -kev ua tau zoo austenitic stainless hlau nrog molybdenum, muab superior tiv thaiv rau chlorides thiab marine ib puag ncig. 3CR12 yog ib tug pob nyiaj siv- phooj ywg ferritic "utility" feem ntau cov hlau tsis muaj steel hlau (1) nyob rau hauv industrial siv.
