Hordhaca 17-4ph Birta Aan-Aabaha ahayn

17-4 saxan bir ah oo aan fiicneyn (630) waa roobab chromium-naxaas ah oo adkeynaya walxaha birta aan fiicnayn ee loo isticmaalo codsiyada u baahan xoog sare iyo heer dhexdhexaad ah oo iska caabin ah.Xoog sare waa
lagu hayo ilaa 600 darajo Fahrenheit (316 darajo
Celsius).

Guryaha Guud

Daawaha birta aan fiicnayn 17-4 PH waa birta adag ee martensitic ahama oo ay ku jiraan Cu iyo Nb/CbDarajada ayaa isku daraysa xoog sare, adayg (ilaa 572°F/300°C), iyo daxalka
iska caabin.

Iska caabinta daxalka

Alloy 17-4 PH waxay u adkeysaneysaa weerarada daxalka ah si ka fiican mid kasta oo ka mid ah birta adag ee adag ee caadiga ah waxayna u dhigantaa Alloy 304 inta badan warbaahinta.

Haddii ay jiraan khataro suurtagal ah oo ah dildilaaca daxalka walaaca, heerkulka gabowgu sareeyo markaas waa in la doortaa in ka badan 1022°F (550°C), gaar ahaan 1094°F (590°C).1022°F (550°C) waa heerkulka ugu fiican ee kulaylka ee warbaahinta chloride.

1094°F (590°C) waa kulaylka ugu fiican ee warbaahinta H2S.

Alwaaxdu waxay ku xiran tahay dildilaac ama weerar haddii ay la kulmaan biyaha badda ee fadhiya muddo kasta.

Waxay u adkaysataa daxalka qaar ka mid ah kiimikooyinka, batroolka, waraaqaha, caanaha iyo warshadaha cuntada (oo u dhiganta darajada 304L).
