Incoloy 925 waa daawaha adag ee adag ee ku salaysan Fe-Ni-Cr alloy oo lagu daray molybdenum, copper, titanium iyo aluminium.Alloy wuxuu leeyahay xoog sare iyo iska caabin daxalka aad u fiican codsiga.Waxa ku jira nikkelku waa ku filan yahay in uu daxalka ka ilaaliyo daxalka iyo dildilaaca ions chloride.Isku darka nikkel, molybdenum iyo naxaas ayaa sidoo kale siinaya alloy iska caabin heer sare ah si loo yareeyo kiimikooyinka.Molybdenum waxay gacan ka geysataa hagaajinta iska caabinta godad iyo daxalka dillaaca.Qaybta chromium ee daawaha waxay bixisaa iska caabbinta oksaydhka ee ka soo horjeeda deegaanka yaraynta.Ku darida titanium iyo aluminium waxay xoojin kartaa daawaynta inta lagu jiro daaweynta kulaylka

Carpenter Alloy 925 waxa loo ogolaaday NACE MR0175.
NACE MR0175
Awood farsamo oo wanaagsan iyo iska caabin ballaaran oo daxalka.
Waxay leedahay iska caabbinta daxalka wanaagsan ee daxalka chloride ion stress, daxalka maxalliga ah iyo yaraynta kala duwan ee warbaahinta kiimikada oxidizing.
Commonl loo isticmaalo qaybaha iyo qaybaha equioment ee saliidda iyo gaaska.sida tuubooyinka, valves, bositioning ioint, qalab ioint packer, oo sidoo kale loo isticmaalo soo saarista xirayaasha qaarkood.
