Thermal Properties thiab Physical Attributes
Qhov sib txawv ntawm microstructural ntawm dual -theem ferritic-austenitic matrix ntawm Duplex 2205 thiab ib zaug -theem FCC (lub ntsej muag-centered cubic) lattice ntawm 904L tsim kom muaj qhov sib txawv ntawm lub cev teb rau qhov kub thiab txias.
Coefficient ntawm Thermal Expansion (CTE):Duplex 2205 nthuav tawm qhov coefficient qis ntawm thermal expansion piv rau 904L. Hauv cov kav dej uas muaj thermal cycling los yog siab -kub cov kauj ruam, 2205 exerts tsawg thermal stress ntawm piping anchors, pob qij txha, thiab flanges, txo txoj kev pheej hmoo ntawm kev sib koom ua ke.
Thermal conductivity:ferritic theem nyob rau hauv Duplex 2205 muab kwv yees li 25% siab dua thermal conductivity tshaj 904L. Qhov no ua rau 2205 qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob sib txuas hluav taws xob, cov txheej txheem txheej txheem reactors, thiab cov ntawv thov uas yuav tsum tau ua kom sov sai sai.
Temperature Threshold Limitations thiab Phase Stability
Kev khiav hauj lwm qhov kub thiab txias ciam teb txiav txim qhov kev ntseeg tau ntawm cov hlau alloys dhau mus txuas ntxiv ntau- xyoo caum kev pabcuam.
1. Siab-Tsuas Kub Txwv thiab Embrittlement
Duplex 2205 txwv:Duplex 2205 yog nruj me ntsis txwv los ntawm kev pabcuam txuas ntxiv ntawm qhov kub siab tshaj300℃(572℃F). Kev raug ncua ntev tshaj qhov txwv no ua rau "475℃embrittlement" (alpha prime theem nag lossis daus) thiab tsim cov nkig intermetallic.sigma theem. Cov kev hloov microstructural no sai degrade cov yeeb nkab tawg toughness thiab corrosion kuj.
904L muaj peev xwm:Dawb los ntawm cov qauv ferritic, 904L tseem tiv thaiv kom tsis txhob muaj 475℃embrittlement. Nws tuav nws cov qauv kev ncaj ncees, siab creep resistance, thiab ductile zog ntawm siab ua hauj lwm kub mus txog rau400℃- 450℃(752℃F - 842℃F), ua rau nws txhim khu kev qha rau kub, concentrated acidic kab.
2. Sub-Zero Performance and Impact Toughness (MDMT)
Yam tsawg kawg nkaus tsim hlau kub (MDMT):904L nta cov qauv siv lead ua austenitic tag nrho uas tsis ua rau lub cev muaj zog - mus rau - nkig hloov. Nws khaws cov khoom siv hluav taws xob zoo tshaj plaws thiab kev ua haujlwm qis mus rau qib cryogenic (-196℃/ -320℃F).
Duplex 2205 txwv:Qhov ferritic feem ntawm Duplex 2205 tau dhau los ua cov ductile - mus rau - nkig hloov raws li qhov kub thiab txias. Raws li tus qauv cov lej zoo li ASME B31.3, tus qauv Duplex 2205 cov yeeb nkab yuav tsum tau ua raws li Charpy V-Kev ntsuas qhov cuam tshuam yog tias tau teev tseg rau cov haujlwm hauv qab no-50 ° F (-58 ° F).
