Astaamaha Duplex Ss 2205
2205 bir ah 4*1mm tuubo duuban
Duplex Stainless Steel 2205 Marka la barbar dhigo 316L iyo 317L austenitic birta aan lahayn, 2205 ayaa ka sarreeya iska caabbinta daxalka.Waxay leedahay iska caabin sare oo daxalka.Marka la barbar dhigo austenite, iskudarkeeda ballaarinta kulaylka ayaa ka hooseeya, kuleylku wuu sarreeyaa.
Duplex Stainless Steel 2205 wuxuu leeyahay laba jeer xoogga isku-buuqa ee birta austenitic, taas oo u oggolaanaysa naqshadeeyayaasha inay yareeyaan miisaankooda marka loo eego 316L iyo 317L.Daawaha 2205 wuxuu si gaar ah ugu habboon yahay in lagu isticmaalo heerkulka -50°F/+ 600°F waxaana loo isticmaali karaa heerkulka hoose ee xaddidaadyo daran (gaar ahaan dhismaha alxanka).
Iska caabbinta daxalka ee 2205 Duplex Stainless Steel
2205 bir ah 4*1mm tuubo duuban
- Daxalka lebbiska ah, Iska caabbinta daxalka ee birta birta ah ee duplex 2205 ayaa ka sareysa 316L iyo 317L inta badan deegaanka sababtoo ah ka kooban chromium (22%), molybdenum (3%), iyo content nitrogen (0.18%).
Ka-hortagga daxalka maxalliga ah, Waxyaabaha ku jira chromium, molybdenum, iyo nitrogen ee ku jira birta laba-laabka ah ee aan lahayn 2205 waxay ka dhigaysaa mid aad u adkeysi badan u leh godadka iyo daxalka dillaaca ee oxidizing iyo xalalka acidic. - Daxalka ka-hortagga walbahaarka, Qaab-dhismeedka laba-laabka ah ee 2205 ee birta aan-ka-qaadka lahayn waxay gacan ka geysataa hagaajinta iska-caabbinta dillaaca daxalka walaaca ee birta-la'aanta ah.Heerkul gaar ah, xaaladaha kacsanaanta, ogsijiinta, iyo chloride, daxalka culeyska kolorida wuxuu ku dhacaa austenitic ahama.Maadaama shuruudahan aan si fudud loo xakameyn karin, isticmaalka 304L, 316L, iyo 317L ayaa xaddidan arrintan.
- Daalka ka-hortagga daxalka, birta dual-waji 2205 xoog sare leh iyo iska caabin daxalka u leh xoogga daalka iska caabinta daxalka sare.Qalabka farsamaynta wuxuu u nugul yahay bay'ad daxalaysa iyo wareegyada rarka, iyo qaababka birta ah ee duplex ee 2205 ayaa si fiican ugu habboon codsiyadaas.
Metallography ee ku saabsan Duplex Ss 2205 uns s31803
Halabuurka kiimikada ee 2205 birta duplex waxay siinaysaa qaab-dhismeedkii la rabay ee 50 ϫ/50 kadib 1900/1922° F(1040°C/1080°C)Haddii heerkulka daawaynta kulaylku ka sarreeyo 2000 ° F, waxay horseedi kartaa korodhka isku-dhafka ferrite.Si la mid ah biraha kale ee duplex-ka ah, 2205 alloys waxay u nugul yihiin roobabka wejiga dhexdhexaadka ah.
Wajiga intermetallic wuxuu soo da'ayaa inta u dhaxaysa 1300 ° F iyo 1800 ° F wuxuuna u soo da'ayaa sida ugu dhaqsaha badan 1600 ° F. Sidaa darteed, waxaan u baahanahay inaan tijaabino 2205, si loo hubiyo in aysan jirin weji dhexdhexaad ah, tixraaca imtixaanka ASTM A 923.
