DUPLEX STAINLESS STEEL HOM QAB THIAB STANDARD

DUPLEX STAINLESS STEEL HOM QAB THIAB STANDARD

•Lean Duplex SS - qis nickel thiab tsis muaj molybdenum - 2101, 2102, 2202, 2304
Duplex SS - ntau dua nickel thiab molybdenum - 2205, 2003, 2404
•Super Duplex - 25Chromium thiab ntau dua nickel thiab molybdenum "ntxiv" - 2507, 255 thiab Z100
•Hyper Duplex – Ntau Cr, Ni, Mo thiab N – 2707

Mechanical Properties:
•Duplex Stainless Steels muaj kwv yees li ob zaug lub zog tawm los ntawm lawv cov qib austenitic.
•Qhov no tso cai rau cov neeg tsim khoom siv cov khoom siv thinner gauge rau kev tsim lub nkoj!

Duplex stainless hlau qhov kom zoo dua:
1. Muab piv nrog austenitic stainless hlau
1) Lub zog tawm los yog ntau tshaj li ob zaug siab dua li ntawm cov hlau tsis zoo austenitic, thiab nws muaj cov yas txaus uas yuav tsum tau ua rau molding. Lub thickness ntawm lub tank los yog lub nkoj siab ua los ntawm duplex stainless hlau yog 30-50% qis dua qhov uas feem ntau siv austenitic stainless hlau, uas yog qhov zoo los txo tus nqi.
2) Nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov tshuaj chloride ions, txawm tias cov duplex alloy nrog cov ntsiab lus qis tshaj plaws muaj zog tiv thaiv kev ntxhov siab ntau dua li austenitic stainless hlau. Kev ntxhov siab corrosion yog ib qho teeb meem tseem ceeb uas zoo tib yam austenitic stainless hlau nyuaj los daws.
3) Feem ntau 2205 duplex stainless hlau siv nyob rau hauv ntau yam xov xwm muaj corrosion kuj zoo dua li qub 316L austenitic stainless hlau, thaum super duplex stainless hlau muaj corrosion kuj. Hauv qee qhov kev tshaj tawm, xws li acetic acid thiab formic acid. Nws tuaj yeem hloov tau high-alloy austenitic stainless hlau thiab txawm tias corrosion-resistant alloys.
4) Nws muaj kev tiv thaiv zoo rau hauv zos corrosion. Piv nrog austenitic stainless hlau nrog tib cov ntsiab lus alloy, nws muaj kev hnav zoo dua thiab kev tiv thaiv corrosion ntau dua li austenitic stainless hlau.
5) Lub austenitic stainless hlau muaj qhov coefficient qis ntawm kev nthuav dav thiab nyob ze rau cov hlau. Nws yog qhov tsim nyog rau kev sib txuas nrog cov pa roj carbon steel thiab muaj qhov tseem ceeb hauv engineering, xws li kev tsim cov phaj sib xyaw lossis cov hauv ob sab phlu.

2. Piv nrog ferritic stainless hlau, qhov zoo ntawm duplex stainless hlau yog raws li nram no:
1) Cov khoom siv kho tshuab dav dav yog siab dua li ntawm ferritic stainless hlau, tshwj xeeb tshaj yog cov yas toughness. Tsis zoo li brittleness li ferritic stainless hlau.
2) Ntxiv nrog rau kev ntxhov siab corrosion, lwm yam hauv zos corrosion kuj zoo dua rau ferritic stainless hlau.
3) Cov txheej txheem ua haujlwm txias thiab kev ua haujlwm txias ua haujlwm zoo dua li ferritic stainless hlau.
4) Kev ua haujlwm vuam zoo dua li ntawm ferritic stainless hlau. Feem ntau, tsis muaj kev kho cua sov yuav tsum tau ua tom qab preheating yam tsis muaj vuam.
5) Daim ntawv thov ntau yog dav dua li ntawm ferritic stainless hlau.

Daim ntawv thovVim lub zog siab ntawm duplex steel, nws nyhav kom txuag tau cov khoom, xws li txo cov phab ntsa thickness ntawm cov yeeb nkab. Kev siv SAF2205 thiab SAF2507W ua piv txwv. SAF2205 yog tsim rau siv nyob rau hauv ib puag ncig uas muaj chlorine thiab yog haum rau siv nyob rau hauv refinery los yog lwm yam txheej txheem xov xwm tov nrog chloride. SAF 2205 yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv lub tshav kub exchangers uas muaj aqueous chlorine los yog dej brackish raws li qhov nruab nrab cua txias. Cov khoom siv kuj tsim nyog rau dilute sulfuric acid daws thiab cov organic acids ntshiab thiab cov khoom sib xyaw. Xws li: roj pipelines hauv kev lag luam roj thiab roj: tshem tawm cov roj crude hauv refineries, purification ntawm sulfur-muaj gases, cov khoom siv kho dej khib nyiab; Cov tshuab cua txias siv cov dej khib nyiab lossis cov tshuaj chlorine uas muaj cov tshuaj.
