Guryaha Guud
Alloy 2205 Duplex saxan bir ahama waa 22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex ahama birta saxan sare oo guud, deegaanka iyo stress guryaha iska caabin daxalka marka lagu daro xoog sare iyo adkaanta saamaynta fiican.
2205 tuubo aan bir lahayn oo duuban
Alloy 2205 duplex ahama birta birta ah waxay bixisaa iska caabin daxalka ah oo ka sarreeya 316L ama 317L austenitic birta aan lahayn ee ku dhawaad dhammaan warbaahinta daxalka leh.Waxa kale oo ay leedahay daxalka sare iyo guryaha daalka nabaad-guurka iyo sidoo kale ballaarinta kulaylka hoose iyo ka-hortagga kulaylka ka sarreeya austenitic.
Xoogga wax-soo-saarku wuxuu ku saabsan yahay labanlaab ka birta austenitic ahama.Tani waxay u oggolaanaysaa naqshadeeyaha inuu badbaadiyo miisaanka oo wuxuu ka dhigayaa daawaha kharash badan oo tartan ah marka la barbardhigo 316L ama 317L.
2205 tuubo aan bir lahayn oo duuban
Alloy 2205 Duplex saxan bir aan lahayn ayaa si gaar ah ugu habboon codsiyada daboolaya heerkulka -50°F/+600°F.Heerkulka ka baxsan xadkan waa la tixgelin karaa laakiin wuxuu u baahan yahay xoogaa xaddidaad ah, gaar ahaan dhismayaasha alxanka.

Iska caabinta daxalka
Daxalka Guud
Sababtoo ah chromium sare (22%), molybdenum (3%), iyo nitrogen (0.18%) waxa ku jira, sifooyinka iska caabbinta daxalka ee 2205 saxan bir ah oo duplex ah ayaa ka sarreeya 316L ama 317L inta badan deegaanka.
Iska-caabbinta Daxalka Deegaan ahaan
Chromium-ka, molybdenum-ka, iyo nitrogen ee ku jira 2205 saxan bir ah oo duplex ah ayaa sidoo kale bixiya iska caabin aad u wanaagsan oo ku wajahan daxalka iyo daxalka dillaaca xitaa xalal aad u oksaydheyn iyo acidic ah.

Qaab-dhismeed-yareedka-duplex-ka waxaa loo yaqaanaa inuu hagaajiyo iska caabbinta daxalka walaaca ee birta aan-daahaalka lahayn.
Dildilaaca daxalka chloride ee biraha austenitic ahama waxay dhici kartaa marka xaaladaha lagama maarmaanka ah ee heerkulka, stress adag, oxygen, iyo chlorides ay joogaan.Mar haddii xaaladahan aan si sahal ah loo koontaroolin, dildilaaca daxalka ayaa inta badan caqabad ku noqday isticmaalka 304L, 316L, ama 317L.

Iska-caabbinta Daalka Daxalka
Alloy 2205 Duplex saxan bir ah oo aan lahayn waxay isku daraysaa xoog sare iyo iska caabin daxalka sare leh si ay u soo saarto xoog daalka daxalka sare.Codsiyada ay ku jiraan qalabka farsamaynta ee ay ku xiran yihiin labadaba jawi si xun u wasakhaysan iyo rarista wareegga waxay ka faa'iideysan karaan sifooyinka 2205 duplex ee saxan birta ah.
