Lub duplex stainless hlau

{{0 {}} Dab tsi yog Duplex Stainless Hlau?

Duplex stainless hlau yog ib qeb ntawm corrosion-resistant alloys muaj pes tsawg tus qauv ntawm ob qho tib si qauv sib xyaw (18-28%), nruab nrab ntawm ob leeg (4-8%), molybdenum (1-5%), thiab nitrogen (0 {}}}}}}} g., 304), lossis martensitic stainless steels.

{{0 {{}} Dab tsi yog qhov tsis zoo ntawm Duplex Stainless Hlau?

Vuam nyuaj:

Vuam yuav cuam tshuam rau lub Austenite-ferrite tshuav nyiaj li cas, uas txo cov khoom siv hluav taws xob (uas txo cov khoom siv hluav taws xob tiv thaiv corrosion {{2}

Tom qab weld kev kho cua sov yog qhov tsis tshua muaj txiaj ntsig, ua cov txheej txheem vuam tseem ceeb heev {}

Tsawg tus formability:

Piv rau austenitic stainless hlau (e .}} ... .}}}}}}}

Magnetism:

Lub Ferrite theem ua rau Duplex cov hlau me ntsis sib nqus, uas yuav ua tsis tau zoo rau cov ntawv thov uas tsis yog cov khoom siv hluav taws xob, qee yam hluav taws xob (qee yam hluav taws xob).

Nqi:

Duplex stainless hlau yog kim dua li cov qhab nia ntawm cov qib qis (}}}}}} Kev Siv .

Rhiab heev rau kev kho cua sov:

Lub sijhawm ntev los ntsuas ntawm 300-500 ° c

{{0 {}} Qhov zoo ntawm cov hlau duplex stainless?

Lub zog siab:

Lub zog ntawm cov khoom siv DUPLAS

Supior corrosion Kuj:

Zoo heev rau chloride-induced kev nyuaj siab corrosion (SCC), pitting, thiab kev muaj kev lag luam uas muaj cov ntsiab lus tseem ceeb tshaj plaws nrog cov chloride cov ntsiab lus.

Kev sib xyaw ntawm chromium, molybdenum, thiab nitrogen nyob rau hauv lub sij hawm dual txhim kho zaj duab xis sab hauv zaj duab xis .

Dev zoo thiab tawv tawv:

Txawm hais tias muaj zog dua, cov hlau yas ua kom muaj kev pheej hmoo ua tiav (elongation) thiab cuam tshuam kev pheej hmoo

Tus nqi ua hauj lwm zoo nyob rau hauv cov ntawv thov tshwj xeeb:

Thaum nws kim dua li cov qauv stainless hlau, lawv lub zog muaj peev xwm txo qis kev tu siab thiab muaj kev pabcuam tsawg dua li cov ntaub ntawv pheej yig dua {}}

Kuj rau oxidation thiab kub siab:

Siab dua cov ntsiab lus chromium muab cov oxidation zoo dua ntawm cov qib kub (txawm tias lawv tsis tsim los rau qee qhov kub siab siv .

{{0 {}} Thaum twg siv Duplex Stainless Hlau?

Duplex Stainless hlau yog qhov zoo tagnrho rau cov ntawv thov uas:

Lub zog siab thiab corrosion tsis kam yog ob qho tseem ceeb:

Offshore roj thiab roj platforms, possea kav dej, thiab cov marine tshuab machinesering) (raug rau dej hiav txwv thiab kev ntsuas siab).

Desalination nroj tsuag, khoom siv tshuaj lom neeg (e {{} g}, brines, sulfuric acid) {{5}

Kev txo phaus yog qhov tseem ceeb:

Cov txheej txheem sib xyaw ua ke hauv nkoj, lossis kev thauj mus los (e {{{}

Kuj mus rau chloride SCC yog tsis muaj kev sib ceg:

Ntawv thiab pulp mills (raug rau chloride-raws li cov chaw tu vaj tse, thiab cov ntug dej hiav txwv}, txuas hniav, seawalls).

Kev Ntsuas Kub-Kub Kuj Xav Tau:

Cheebtsam hauv lub hwj chim tiam, kev hloov cua sov, lossis cov cua sov ua haujlwm hauv qab no ~ 800 ° C, qhov twg Oxidation Resistance yog yuav tsum {}}

5. Tau} Tau Duplex stainless hlau yuav tawv?

Txwv kev kho cua sov:
Lub stuplex stainless hlau tsis tuaj yeem ua kom muaj kev sib tw ua ke, yog li kev kho kom sov thiab cua sov theem ntau dua li nce hardness.

Txias ua haujlwm rau hardening:
Txias ua haujlwm (e {{{{0} g} {1} {} Txawm li cas los xij Formarity cov cai yuav tsum tau .

Lwm txoj kev tawv:
Cov txheej txheem tawv tawv tawv zoo li nitriving lossis tua chanening los siv tau los txhim kho cov npoo tawv rau cov khoom tseem ceeb {}}
