Biraha birta aan lahayni waa biro-daawaha sare leh oo iska caabbinta daxalka sare leh marka loo eego birta kale sababtoo ah joogitaanka xaddi badan oo chromium ah. Iyada oo ku saleysan qaab dhismeedkooda crystalline, waxay u sii kala qaybsan yihiin birta birta ah, austenitic, iyo martensitic.
Fasalka 309 birta daxalka ah waxay leedahay iska caabin daxalka sare leh iyo xoog marka la barbar dhigo 304 birta daxalka ah. Xaashidan xogeed ee soo socota waxay bixinaysaa dulmar guud ee darajada 309 ee birta aan-kala-baxa lahayn.
Guryaha Guud
Alloy 309 (UNS S30900) waa bir ahama austenitic ah oo loo sameeyay in lagu isticmaalo codsiyada iska caabinta daxalka heerkulka sare. Daawaha waxay ka hortagtaa oksaydhka ilaa 1900°F (1038°C) ee hoos yimaada xaalado aan meerto ahayn. Baaskiil kuleyleedka joogtada ah wuxuu yareeyaa caabbinta oksaydhka ilaa 1850°F (1010°C).
Sababtoo ah chromium sare iyo waxa ku jira nikkel hooseeya, Alloy 309 waxa lagu isticmaali karaa baaruud ka kooban jawi ilaa 1832°F (1000°C). Daawaha laguma talinayo in lagu isticmaalo jawiyada karbohidraatka aadka u sarreeya maadaama ay muujiso iska caabin dhexdhexaad ah oo keliya nuugista kaarboonka. Alloy 309 waxaa loo isticmaali karaa wax yar oksaydhaynta, nitriding, sibidhka iyo codsiyada baaskiil wadida kulaylka, inkastoo, heerkulka adeegga ugu badan waa in la dhimo.
Marka la kululeeyo inta u dhaxaysa 1202 – 1742°F (650 – 950°C) alwaaxdu waxay ku xidhan tahay roobab wejiga sigma. Xalka daawaynta nuugista ee 2012 – 2102°F (1100 – 1150°C) waxay soo celin doontaa heerka adkaanta.
309S (UNS S30908) waa nooca kaarboonka hooseeya ee daawaha. Waxaa loo isticmaali karaa si fudud in la sameeyo. 309H (UNS S30909) waa wax ka beddelka kaarboonka sare ee loo sameeyay caabbinta gurguurta ee la xoojiyey. Inta badan cabbirka hadhuudhka iyo kaarboonka saxanka ayaa buuxin kara shuruudaha 309S iyo 309H labadaba.
Alloy 309 si fudud ayaa loo alxan karaa oo looga baaraandegi karaa hab-dhaqannada wax-soo-saarka dukaanka caadiga ah.
