Cov khoom siv dab tsi yog Duplex Stainless Hlau

Cov khoom siv dab tsi yog duplex stainless hlau

Duplex stainless hlau yog cov hlau uas muaj cov khoom tshwj xeeb austenitic thiab ferritic. Nws muaj qhov sib npaug sib npaug ntawm ob hom, muab qhov zoo tshaj plaws ntawm txhua hom. Austenitic steels paub txog lawv lub zog siab, thaum ferritic steels muaj kev tiv thaiv zoo heev.

Qhov tshwm sim yog ib qho alloy uas muaj kev ua tau zoo nyob rau hauv ib puag ncig hnyav uas lwm cov hlau yuav poob qis. Duplex stainless hlau yog dav siv nyob rau hauv ntau yam industries xws li tshuaj ua, roj thiab roj, thiab marine engineering.

Cov hlau no tau dhau los ua neeg nyiam vim nws muaj peev xwm tshwj xeeb los tswj nws cov khoom siv kho tshuab thiab lub cev txawm tias nyob rau hauv qhov kub hloov pauv lossis kub siab. Tsis tas li ntawd, duplex stainless hlau yeeb nkab yog ntau resistant rau cracking los ntawm kev nyuaj siab corrosion dua li ntau lwm yam ntaub ntawv nyob rau hauv lub lag luam. Duplex stainless hlau raj tau dhau los ua ib qho ntawm cov khoom siv tshaj plaws rau cov neeg saib xyuas kom lub neej ntev thiab kev ua haujlwm ntawm lawv cov haujlwm.

Los ntawm cov choj thiab cov kav dej mus rau cov cuab yeej kho mob thiab cov tsev tsim khoom - cov khoom siv ntau yam no tuaj yeem pom nyob txhua qhov chaw!

Duplex steel yog cov hlau uas sib xyaw ua ke zoo ntawm austenitic thiab ferritic stainless hlau. Cov muaj pes tsawg leeg ntawm duplex stainless hlau feem ntau muaj chromium, nickel, molybdenum thiab nitrogen. Tus nqi ntawm txhua lub ntsiab lus nyob rau hauv muaj pes tsawg leeg yuav txawv nyob ntawm seb cov qib tshwj xeeb los yog alloy. Txawm li cas los xij, feem ntau, duplex stainless hlau muaj cov ntsiab lus chromium ntau dua (kwv yees li 22%) dua li cov pa austenitic stainless hlau. Cov ntsiab lus siab ntawm chromium muab nws zoo heev corrosion kuj. Ntxiv nrog rau chromium, duplex stainless hlau muaj kwv yees li 5-8% npib tsib xee, uas muab ntxiv zog thiab toughness. Molybdenum tau ntxiv los txhim kho kev tiv thaiv pitting corrosion, thaum nitrogen pab txhim kho cov khoom siv. Kev sib xyaw ua ke ntawm cov ntsiab lus no ua rau muaj zog thiab corrosion kuj piv rau lwm hom stainless hlau. Nws yog ib nqi sau cia hais tias cov qib sib txawv nyob rau hauv lub duplex stainless hlau tsev neeg muaj sib txawv compositions - qhov no tso cai rau lawv siv nyob rau hauv ntau yam kev siv, xws li tshuaj ua khoom siv los yog refineries qhov twg hnyav ib puag ncig.
