X5CrNiMo17-12-2 khoom yog dab tsi?
X5CrNiMo17-12-2 (Material No. 1.4401) yog German-standard (DIN/EN) molybdenum-bearing austenitic stainless hlau; nws feem ntau yog raws li tus qauv thoob ntiaj teb AISI 316 lossis qib hauv tsev 06Cr17Ni12Mo2. Vim tias qhov sib ntxiv ntawm kwv yees li 2.0% -2.5% molybdenum, nws tsis kam mus rau chloride pitting thiab crevice corrosion yog superior rau ntawm 304 stainless hlau. Nws tuaj yeem ua tiav rau hauv ntau hom khoom siv, nrog rau cov phaj, coils, raj, tuav, xov hlau, thiab lwm yam. Rau cov ncauj lus kom ntxaws chemical muaj pes tsawg leeg specifications lossis thov cov qauv dawb, thov hu rau peb lub Hoobkas tam sim ntawd.
X5CrNiMo17-12-2 khoom sib npaug yog dab tsi?
Cov ntaub ntawv sib npaug rau X5CrNiMo17-12-2 (European Standard EN 1.4401) feem ntau suav nrog AISI 316 (US Standard), SUS 316 (Japanese Standard), thiab raws li Suav cov qauv 06Cr17Ni12Mo2 lossis 12Mo17N; nws yog feem ntau siv nyob rau hauv marine ib puag ncig, cov khoom siv tshuaj, cov cuab yeej kho mob, thiab cov khoom noj khoom haus qib siab.

X5CrNiMo17-12-2 Stainless hlau: Kev kho cua sov
Thaum tshav kub kub kev kho mob Specification: tshuaj annealing ntawm 1010-1150 degree, ua raws li los ntawm ceev ceev.
X5CrNiMo17-12-2 Stainless Hlau: Forging
Workpieces ua los ntawm X5CrNiMo17-12-2 stainless hlau feem ntau preheated rau qhov kub ntawm 1150℃thiab 1180 degree. Forging yog ua nyob rau hauv qhov kub ntawm 1180℃rau 950 degree. Tom qab forging, lub workpieces yuav tsum tau txias sai sai hauv huab cua lossis dej kom tsis txhob muaj cov theem tsis zoo uas yuav cuam tshuam cov khoom siv kho tshuab. Discoloration los yog scale tsim yuav txo tau corrosion kuj thiab yuav tsum tau muab tshem tawm ntawm pickling los yog lwm yam tsim nyog txheej txheem.
X5CrNiMo17-12-2 Stainless Hlau: Weldability
X5CrNiMo17-12-2 stainless hlau pom zoo weldability, txawm tias welded nrog lossis tsis muaj cov hlau muab tub lim. Yog hais tias yuav tsum tau muab tub lim hlau, Qib 1.4430 yuav raug siv, nrog rau qhov siab tshaj plaws interpass kub ntawm 150 degree. Vim nws cov ntsiab lus ntawm cov pa roj carbon ntau, nws muaj peev xwm ua rau chromium carbide tsim-uas txo qis kev tiv thaiv rau intergranular corrosion txhais tau hais tias tom qab vuam cua sov yuav tsim nyog. Yog tias thaj chaw loj yuav tsum tau vuam, kev siv qib 1.4404 (X2CrNiMo17-12-2) raug pom zoo.
X5CrNiMo17-12-2 Stainless Hlau: Corrosion Resistance
Lub PREN (Pitting Resistance Equivalent Number) rau X5CrNiMo17-12-2 stainless hlau nyob ntawm 23.1 txog 28.5. Ua tsaug rau cov hlau cov ntsiab lus molybdenum (2-2.5%), nws cov kev tiv thaiv rau pitting thiab chloride-induced corrosion yog txhim kho; Yog li ntawd, qhov kev tiv thaiv corrosion ntawm Qib 1.4401 yog qhov zoo dua rau cov qib stainless hlau 1.4301 thiab 1.4307.
X5CrNiMo17-12-2 vs X2CrNiMo17-12-2
X2CrNiMo17-12-2 (1.4404) thiab X5CrNiMo17-12-2 (1.4401) yog ob qho tib si austenitic stainless hlau (tshwj xeeb, qib 316/316L) uas tau siv dav rau lawv cov corrosion kuj zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride. Thawj qhov sib txawv ntawm ob qhov lus dag nyob rau hauv lawv cov ntsiab lus carbon: 316L muaj tsawg dua lossis sib npaug ntawm 0.03% carbon, yog li muab qhov zoo tshaj plaws weldability thiab tsis kam mus rau intergranular corrosion; conversely, 316 muaj tsawg dua los yog sib npaug rau 0.07% carbon thiab muaj zog dua me ntsis.
