General Properties
Alloy 2205 duplex stainless hlau phaj yog 22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex stainless hlau phaj nrog siab dav, thaj chaw thiab kev ntxhov siab corrosion kuj muaj zog ntxiv rau lub zog thiab zoo heev cuam tshuam toughness.
Alloy 2205 duplex stainless hlau phaj muab pitting thiab crevice corrosion kuj superior rau 316L los yog 317L austenitic stainless hlau nyob rau hauv yuav luag tag nrho cov corrosive media. Nws kuj muaj cov khoom zoo corrosion thiab yaig qaug zog nrog rau qis thermal expansion thiab thermal conductivity ntau dua li austenitic.
Lub zog tawm los yog li ob npaug ntawm austenitic stainless hlau. Qhov no tso cai rau tus tsim kom txuag tau qhov hnyav thiab ua rau cov alloy ntau tus nqi sib tw thaum piv rau 316L lossis 317L.
Alloy 2205 duplex stainless hlau phaj yog tshwj xeeb tshaj yog haum rau daim ntaub ntawv npog qhov kub ntawm -50 ° F / + 600 ° F. Kev ntsuas kub sab nraud qhov no yuav raug txiav txim siab tab sis xav tau qee qhov kev txwv, tshwj xeeb tshaj yog rau cov qauv welded.
Daim ntawv thov
● Cov hlab ntsha siab, tso tsheb hlau luam, cov kav dej, thiab cov khoom siv hluav taws xob sib txawv hauv kev lag luam tshuaj
● Cov kav dej, tubing, thiab cov khoom siv hluav taws xob sib txawv rau kev tuav cov roj thiab roj
● Cov tshuab ntxhua khaub ncaws
● Pulp thiab paper industry digesters, bleaching equipment, and stock-handling systems
● Rotors, kiv cua, shafts, thiab xovxwm yob yuav tsum tau ua ke lub zog thiab corrosion kuj
● Cargo tanks rau nkoj thiab tsheb thauj khoom
● Cov khoom siv ua zaub mov
● Biofuels nroj tsuag
General Corrosion
Vim tias nws cov chromium siab (22%), molybdenum (3%), thiab nitrogen (0.18%) cov ntsiab lus, cov khoom tiv thaiv corrosion ntawm 2205 duplex stainless hlau phaj zoo dua li ntawm 316L lossis 317L hauv ntau qhov chaw.
Localized Corrosion Resistance
Cov chromium, molybdenum, thiab nitrogen hauv 2205 duplex stainless hlau phaj kuj muab kev tiv thaiv zoo heev rau pitting thiab crevice corrosion txawm nyob rau hauv heev oxidizing thiab acidic daws.
Isocorrosion Curves 4 mpy (0.1 mm / xyoo), nyob rau hauv sulfuric acid tov muaj 2000 ppm
Kev nyuaj siab Corrosion Resistance
Lub duplex microstructure yog paub los txhim kho cov kev ntxhov siab corrosion cracking kuj ntawm stainless hlau.
Chloride stress corrosion cracking ntawm austenitic stainless hlau tuaj yeem tshwm sim thaum muaj qhov tsim nyog ntawm qhov kub thiab txias, tensile stress, oxygen, thiab chlorides. Txij li cov xwm txheej no tsis yooj yim tswj tau, kev ntxhov siab corrosion tawg feem ntau yog ib qho teeb meem rau kev siv 304L, 316L, lossis 317L.
