Iska caabinta daxalka

904L waa kaarboon yar oo hooseeya, bir aan lahayn austenitic alloying sare oo loogu talagalay bay'ada daxalka adag.Waxay leedahay iska caabbinta daxalka oo ka fiican 316L iyo 317L, iyada oo la dheellitirayo qiimaha iyo waxqabadka, waxayna leedahay wax-ku-oolnimo sare.Sababtoo ah ku darida 1.5% naxaas, waxay leedahay iska caabin aad u wanaagsan oo hoos u dhigista asiidhyada sida sulfuric acid iyo phosphoric acid.Waxa kale oo ay leedahay iska caabin aad u fiican oo ay u leedahay daxalka stress-ka, daxalka godka, iyo daxalka dillaaca ee ay keento ions koloride, oo ay iska caabin fiican u leedahay daxalka intergranular.Sulfuric acid saafi ah oo leh qiyaasta 0-98%, heerkulka isticmaalka ee 904L wuxuu gaari karaa ilaa 40 darajo Celsius.Aashitada fosfooraska saafiga ah oo leh xaddiga fiirsashada ee 0-85%, iska caabbinta daxalka ayaa aad u wanaagsan.Najaasadu waxay saameyn xooggan ku leedahay caabbinta daxalka ee fosfooraska aashitada warshadaha oo ay soo saarto tignoolajiyada habka qoyan.Dhammaan noocyada fosfooraska acid, 904L ayaa iska caabbinta daxalka ka fiican marka loo eego birta aan caadiga ahayn.Nitric acid oxidizing aadka u sarreeya, 904L waxay leedahay iska caabbinta daxalka hoose marka la barbar dhigo darajooyinka birta alloydhka sare ee aan lahayn molybdenum.Hydrochloric acid, isticmaalka 904L waxay ku xaddidan tahay uruurinta hoose ee 1-2%.Xaddigan fiirsiga dhexdiisa.Iska caabbinta daxalka ee 904L ayaa ka fiican kan birta aan caadiga ahayn.Birta 904L waxay leedahay iska caabin sare oo u ah daxalka.U adkaysiga daxalka dillaaca ee xalka chloride.Xoogga ayaa sidoo kale aad u wanaagsan.Maadada sare ee nikkel ee 904L waxay yaraynaysaa heerka daxalka ee godadka iyo godadka.Sida caadiga ah ee austenitic ahama waxa laga yaabaa inay dareento daxalka culayska ee deegaan qani ku ah chloride heerkulka ka sarreeya 60 darajo Celsius.Iyadoo la kordhinayo maadada nikkel ee birta aan nadiifka ahayn, dareenkan waa la yarayn karaa.Maaddaama ay ka kooban tahay nikkel sare, 904L waxay soo bandhigaysaa iska caabin sare oo dillaaca daxalka walaaca ee xalalka chloride, xalalka hydroxide ee xoogga leh, iyo bay'ada qani ku ah hydrogen sulfide.
