Cov Hlau Stainless vs. Cov Hlau Stainless Duplex

1. Dab tsi yog stainless hlau? Dab tsi yog duplex stainless hlau?

Cov hlau tsis xeb yog ib lo lus dav dav rau ib hom hlau uas tiv taus xeb, thiab nws cov hom feem ntau yog muab faib ua pawg raws li cov qauv me me. Cov feem ntau suav nrog cov hlau tsis xeb austenitic (xws li 304, 316) thiab cov hlau tsis xeb ferritic. Cov hlau tsis xeb duplex yog ib hom tshwj xeeb uas nws cov qauv me me yog sib xyaw ua ke kwv yees li ib nrab ntawm ferrite thiab austenite.

2. Cov txiaj ntsig tseem ceeb ntawm duplex stainless hlau yog dab tsi?

(1)Lub zog siab heev:Nws lub zog tso zis yog li ob npaug ntawm cov hlau austenitic stainless hlau, uas txhais tau tias hauv cov ntawv thov xws li cov hlab siab, cov ntaub ntawv nyias dua tuaj yeem siv los ua kom tau raws li qhov xav tau ntawm lub zog thiab ua tiav qhov hnyav thiab txo nqi.

(2)Kev tiv thaiv kev ntxhov siab zoo heev (SCC):Hauv ib puag ncig uas muaj chlorine ions, cov hlau austenitic stainless hlau ib txwm (xws li 304) yog qhov yooj yim rau kev ntxhov siab corrosion cracking, thaum duplex stainless hlau muaj qhov zoo ntuj hauv qhov no, thiab nws cov kev ua tau zoo dua li ntawm 300 series austenitic hlau.

3. Puas muajpuas muaj kev txwv ntawm duplex stainless hlau?

(1) Qhov kub siv tau txwv:Vim nws qhov nruab nrab kub brittleness cheeb tsam xws li "475 ° C brittleness", nws feem ntau tsis pom zoo kom siv ntev hauv qhov kub siab tshaj 250 ° C-300 ° C;

(2) Kev ua tiav thiab vuam cov kev cai nruj:Nws cov nyhuv ua haujlwm txias yog loj, nws cov yas thiab toughness qis dua li cov hlau tsis xeb austenitic, thiab nws txoj kev tsim yog qhov nyuaj. Lub zog kab thiab qhov txias yuav tsum tau tswj hwm nruj me ntsis thaum lub sijhawm vuam kom tiv thaiv cov dej nag ntawm cov theem phom sij thiab rhuav tshem qhov sib npaug ntawm ob theem.

4. Yuav xaiv li cas ntawm ob qho no?

Yog tias qhov xwm txheej ntawm daim ntawv thov muaj qhov yuav tsum tau muaj zog siab thiab ntsib qhov kev pheej hmoo ntawm kev xeb ntawm chloride (xws li kev tsim kho hauv dej hiav txwv, cov khoom siv tshuaj lom neeg), duplex stainless hlau yog qhov kev xaiv zoo dua;

Yog tias qhov kev pabcuam cuam tshuam nrog qhov kub thiab txias siab lossis xav tau kev tsim txias nyuaj, cov hlau tsis xeb austenitic yuav tsim nyog dua.

Hauv kev xaus, cov hlau tsis xeb thiab cov hlau duplex stainless hlau txhua tus muaj lawv tus kheej qhov zoo, thiab qhov tseem ceeb rau kev xaiv yog nyob rau hauv qhov sib phim qhov kub, kev ntxhov siab thiab corrosive nruab nrab ntawm cov xwm txheej ua haujlwm.
