Duplex Stainless hlau

2205 Stainless hlau

Duplex stainless hlau qib 2205 (tseem hu ua UNS S31803 / S32205, ASTM A240 Hom 2205, Inox 2205, AISI 318LN, SUS 329J3L, lossis EN 1.4462) yog ob theem (ferritic% 2-au) alloys. chromium, 2.5-3.5% molybdenum, 4.5-6.5% nickel, thiab roughly 0.15% nitrogen. Nws qhov sib npaug microstructure muab kev sib xyaw tshwj xeeb ntawm lub zog siab thiab zoo heev corrosion kuj. Piv txwv li, qib 2205 feem ntau muaj kwv yees li ob npaug ntawm cov khoom muaj zog ntawm 316L stainless hlau, tso cai rau cov neeg tsim khoom siv ntau qhov sib dua, sib dua yam tsis muaj kev txi.

Cov hlau feem ntau yog muab nkag rau hauv qhov kev daws teeb meem (ib ASTM A240 / A240M) kom khaws cov qauv duplex zoo tagnrho. Qib 2205 tseem tawv los ntawm qhov kub thiab txias (nyob ib ncig ntawm -50 ° C) txog li +300 ° C; Tshaj li qhov ntau, nkig sigma theem tuaj yeem tsim hauv welds. Cov khoom no ua rau duplex 2205 ib qho kev xaiv zoo tshaj plaws rau kev thov xws li kev ua tshuaj lom neeg, offshore roj & roj, thiab marine ib puag ncig uas yuav tsum tau muaj zog thiab chloride corrosion kuj.

Cov txiaj ntsig tseem ceeb ntawm Duplex 2205

Exceptional Strength-rau-Weight Ratio: Qib 2205 muab lub zog tawm los kwv yees li ob npaug ntawm cov khoom siv austenitic stainless hlau. Qhov no tso cai rau cov khoom siv (cov nkoj, tso tsheb hlau luam, cov kav dej, thiab lwm yam) los ua 30-50% thinner, txo qhov hnyav thiab cov nqi khoom siv thaum tuav cov kev ntsuas tib lub siab lossis lub peev xwm thauj khoom.

Qhov zoo tshaj plaws Corrosion Resistance: Lub siab chromium, molybdenum, thiab nitrogen cov ntsiab lus muab 2205 stainless hlau zoo dua qub corrosion tsis kam tshaj 316L / 317L. Nws tiv taus pitting thiab crevice corrosion nyob rau hauv chloride-cov kabmob ib puag ncig zoo tshaj 300-series qib. Hauv kev tawm tsam hnyav lossis dej hiav txwv, duplex 2205 feem ntau ua tau zoo dua cov pa austenitics; super duplex alloys tuaj yeem hloov pauv cov nickel alloys kim dua nyob rau hauv qhov hnyav tshaj plaws.

Superior Stress Corrosion Cracking Resistance:Lub duplex microstructure muab tshwj xeeb tsis kam rau chloride stress corrosion cracking (SCC). Txawm tias cov qib lean duplex deb tshaj 304/316 stainless hauv SCC xeem. Qhov no ua rau 2205 zoo tagnrho rau qhov chaw ntub dej, ntsev, lossis qhov chaw tsis zoo (kev siv dej hiav txwv, kev ua kom dej, dej hiav txwv txias, thiab lwm yam) qhov twg austenitic steels yuav tawg hauv kev ntxhov siab.

Siab Toughness thiab Fatigue Strength: Duplex 2205 tuav zoo heev toughness (txawm tias nyob rau hauv qis-zero kub) thiab resists tawg kev loj hlob nyob rau hauv cyclic loading zoo dua li sib npaug austenitic alloys. Nws absorbs ntau zog nyob rau hauv kev cuam tshuam los yog kev co, ua kom nws muaj zog nyob rau hauv dynamic los yog thaum muaj xwm ceev loads. Nws hardness ntau dua piv rau annealed 304/316 kuj muab kev txhim kho hnav tsis kam nyob rau hauv abrasive tej yam kev mob.

Tsawg Thermal Expansion thiab Carbon-Steel Compatibility:Qib 2205 muaj qhov coefficient tsawg ntawm thermal expansion (ze ntawm cov hlau). Qhov no yog qhov zoo thaum vuam los yog clad laminating rau carbon steel, vim tias qhov kev nthuav dav zoo sib xws txo kev ntxhov siab thiab cuam tshuam. Nws kuj tseem muaj qhov ruaj khov ntawm qhov ntsuas kub hloov pauv zoo dua li 300-series alloys.

Chemical thiab Process Industries: Qhov zoo tshaj plaws rau cov hlab ntsha siab, cov tso tsheb hlau luam siab, cov kav dej, thiab cov khoom siv hluav taws xob hauv cov nroj tsuag tshuaj, cov kua qaub, thiab petrochemical refineries. Nws tuav corrosive acids, alkalis, thiab cov kuab tshuaj uas 300-series stainless yuav ua tsis tau.

Roj, Roj thiab Offshore: Siv nyob rau hauv pipelines, risers, separators, thiab platform Cheebtsam. Nws tsis kam mus rau chloride kev nyuaj siab corrosion cracking ua rau nws muaj txiaj ntsig rau seawater txhaj tshuaj twj tso kua mis, cov kav dej ntsev, thiab cov chaw hauv dej hiav txwv hauv kev tshawb nrhiav offshore thiab ntau lawm.

Kev Kho Dej thiab Desalination: Ua hauj lwm hauv seawater cooling systems, desalination plant, and wastewater treatment. Duplex 2205's pitting kuj ua kom lub neej ua haujlwm ntev hauv kev sib cuag nrog cov brine lossis dej kho.

Pulp & Ntawv Kev Lag Luam: Siv nyob rau hauv digesters, bleaching towers, thiab tshuaj cia tanks. Nws tiv taus qhov kub thiab txias thiab tshuaj lom neeg (xws li chlorine dioxide thiab caustic cawv) ntsib hauv cov txheej txheem pulping thiab bleaching.

Khoom noj khoom haus, dej haus thiab tshuaj ua: Haum rau cov tso tsheb hlau luam, cov kav dej, thiab cov khoom siv hauv kev ua zaub mov, brewing, khoom noj siv mis, thiab cov chaw muag tshuaj. Nws muaj lub zog thiab kev tiv thaiv corrosion raws li kev tu huv huv thiab kev tu cev.

Industrial Machinery thiab Marine Cheebtsam: Siv nyob rau hauv lub twj tso kua mis thiab valve qhov chaw, impellers, shafts, thiab structural Cheebtsam uas yuav tsum tau muaj zog thiab corrosion kuj. Kuj tseem siv rau hauv kev tsim cov nkoj nkoj, cov qauv hauv ntug dej hiav txwv, thiab cov thawv thauj khoom raug mob hnyav.

Lwm yam kev siv engineering: Txhua qhov chaw yuav tsum muaj kev sib xyaw ua ke ntawm lub zog siab, toughness, thiab corrosion kuj. Piv txwv muaj xws li fasteners, flanges, kub exchanger tubing, thiab cov khoom siv nyob rau hauv lub zog tsim, mining, thiab kev tsim khoom.
