Cov lus nug nquag
Q: Duplex 2205 yeeb nkab puas tuaj yeem siv rau hauv dej hiav txwv?
Yog lawm, Duplex 2205 muaj kev tiv thaiv zoo rau cov dej hiav txwv ntws thiab tau siv dav hauv cov kav dej hiav txwv. Txawm li cas los xij, rau qhov tsis muaj zog lossis qis dua - dej hiav txwv ntws ntawm qhov kub siab tshaj ~ 20 degree, super duplex 2507 tej zaum yuav nyiam vim nws cov nqi PREN siab dua (42 vs 35).
Q: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau Duplex 2205?
Qhov kev pom zoo siab tshaj plaws ua haujlwm kub kub rau Duplex 2205 yog 300℃(572℃F). Saum toj no, lub duplex microstructure tuaj yeem hloov pauv theem tsis zoo (475℃embrittlement thiab sigma theem nag lossis daus saum 300 degree).
Q: Puas yog tom qab-weld kev kho cua sov xav tau rau Duplex 2205?
Rau feem ntau cov ntawv thov, tom qab-weld kev kho cua sov tsis tas yuav tsum tau yog tias cov txheej txheem vuam raug ua raws (tswj cov khoom siv hluav taws xob 0.5-2.5 kJ / mm, interpass kub tsawg dua lossis sib npaug li 150℃). Txawm li cas los xij, kev daws teeb meem annealing ntawm 1020-1100℃tom qab dej quenching yuav raug teev rau kev pabcuam tseem ceeb.
Q: Dab tsi vuam consumables siv rau Duplex 2205?
Rau TIG/GTAW: ER2209 muab tub lim. Rau SMAW: E2209-15/16 electrodes. Cov khoom siv no feem ntau yog dhau-alloyed nrog npib tsib xee (8-10%) kom ntseeg tau qhov tseeb austenite-ferrite tshuav nyiaj li cas hauv cov hlau vuam.
