Dab tsi koj yuav tsum paub txog 2205 duplex stainless hlau

2205 duplex stainless hlau yog tsim los ntawm 22% chromium, 3% molybdenum thiab 4.5% nickel nitrogen alloy (austenite-ferrite) duplex stainless hlau (2205 duplex steel). 2205 duplex stainless hlau yog nitrogenous duplex stainless hlau, uas muaj lub zog siab, zoo cuam tshuam toughness thiab zoo zuag qhia tag nrho thiab lub zos tiv thaiv kev nyuaj siab corrosion. 2205 duplex steel yog tshwj xeeb tshaj yog haum rau qhov kub ntawm -50 degree F / +600 degree F. Cov ntawv thov dhau qhov ntsuas kub no kuj tseem yuav xav txog qhov alloy no.

2205 duplex stainless hlau lub cev thiab txhua yam khoom

Qhov ceev: 8. 0g/cm3

Tensile zog: σb Ntau dua lossis sib npaug rau 620Mpa.

Yield zog: σ0.2 Ntau dua lossis sib npaug rau 450Mpa

Elongation: δ Ntau dua lossis sib npaug li 25%.

2205 duplex stainless hlau corrosion kuj
 

1, tsis zoo corrosion: vim cov ntsiab lus chromium ntawm 2205 duplex steel (22%), molybdenum (3%) thiab nitrogen cov ntsiab lus (0.18%), corrosion kuj ntawm 2205 yog zoo dua 316L thiab 317L hauv feem ntau ib puag ncig.

2. Local corrosion kuj: cov ntsiab lus ntawm chromium, molybdenum thiab nitrogen nyob rau hauv 2205 duplex steel ua rau nws muaj zog tsis kam mus rau taw tes corrosion thiab gap corrosion nyob rau hauv oxidizing thiab acidic daws.

3, kev nyuaj siab corrosion kuj: 2205 duplex steel duplex microstructure pab txhim kho cov kev tiv thaiv kev ntxhov siab corrosion cracking peev xwm ntawm stainless hlau. Ntawm qhov kub thiab txias, nro, oxygen thiab chloride muaj, austenitic stainless hlau yuav muaj chloride kev nyuaj siab corrosion. Vim tias cov xwm txheej no tsis yooj yim los tswj, kev siv 304L, 316L thiab 317L yog txwv rau qhov no.

4, corrosion qaug zog tsis kam: 2205 duplex steel lub siab lub zog thiab corrosion kuj ua rau nws muaj zog corrosion qaug zog. Cov cuab yeej ua haujlwm raug cuam tshuam rau qhov chaw corrosive thiab thauj mus los, thiab 2205 nta yog qhov zoo tagnrho rau cov ntawv thov no.

Peb, 2205 duplex stainless hlau qauv

Cov tshuaj muaj pes tsawg leeg ntawm 2205 duplex steel tom qab 1900 degree / 1922 degree F (1040 degree / 1080 degree) cov khoom siv tshuaj annealing, qhov zoo tagnrho microstructure ntawm 50 / 50 tuaj yeem tau txais.
