Alloy 28waa bir austenitic ahama oo ujeedo badan leh oo ujeedo badan leh oo loogu talagalay adeega xaaladaha aadka u wasakhaysan. Darajada waxaa lagu gartaa:
- Iska caabbinta daxalka aadka u sarreeya ee asiidhyada xooggan
- Iska caabin aad u wanaagsan oo loogu talagalay dillaaca daxalka cadaadiska (SCC) iyo daxalka intergranular ee deegaanno kala duwan
- Iska caabbinta sare ee godad iyo daxalka dillaaca
- Weldability wanaagsan

Sababo la xiriira sifooyinka daxalka ee aadka u wanaagsan, Sanicro® 28 waxaa loo isticmaali karaa meelaha ugu kala duwan. Hoos waxaa ku taxan dhowr tusaale oo ah codsiyada kuwaas oo alloy-kani uu si gaar ah ugu habboon yahay.
Fosfooraska acid
Maanta,Alloy 28 amaSanicro 28 waa maadada biraha ah ee loogu isticmaalka badan yahay tuubooyinka uumiga ee soo saarista fosfooraska aashitada habka "qoyan". Dhowr cutub ayaa hadda shaqaynayey in ka badan 10 sano. Heerarka kulaylka garaafka, oo lagu beddelay Sanicro 28, ayaa inta badan lahaa dhibaatooyin soo noqnoqda ee tuubooyinka jabay iyo luminta wax soo saarka.
Sulfuric acid
Alloy 28 amaSanicro 28 waa walxo ku haboon tuubbooyinka iyo kuleyl bixiyayaasha, gaar ahaan inta u dhaxaysa 40 iyo 70% ee acid deaerated iyo in ka badan 85%.Alloy 28 amaSanicro 28 waxay leedahay ku dhawaad iska caabin la mid ah tan Alloy C ee ku jirta aashitada xoogga leh (98% H2SO4).
Saliid iyo gaas
Alloy 28 amaSanicro 28 waxaa loo isticmaalaa tuubooyinka wax soo saarka, daasadaha iyo mashiinnada gaaska qoto dheer, gaaska dhanaan. Maaddada ayaa sidoo kale lagula talinayaa ceelasha saliidda leh ee deegaanka daxalka leh. Ujeedadaas awgeed, tuubooyinka waxaa la siiyaa qabow duuban oo leh xoog sare. Xalka xaalad la tirtiray,Alloy 28 amaSanicro 28 waxa kale oo loo isticmaalaa sida tuubooyin lagu qaado saliida wasakhaysan iyo gaasta iyo kulaylka ku beddelashada xarumaha daawaynta. Xadhkaha Sanicro 28 waxaa loo isticmaalaa hoos u dhigista agabka iyo xakamaynta aaladaha ceelasha saliidda iyo gaaska qoto dheer.
Warbahinta Fluoride-qaadka
Fluoride-sida gaasas-ka-baxa waxay sameyn kartaa inta lagu guda jiro soosaarka fosfooraska acid iyo bacriminta isku dhafan. Gaasaska ka baxsan waa in la tuuraa sababo deegaan dartood. Sanicro 28 ayaa ku habboon ujeedadan. Tijaabooyinku waxay muujiyeen inay ka door bidayaan darajooyinka CrNiMo alloyed ee sarreeya ee soo kabashada gypsum-ka fluoride-ka.
Warshadaha tamarta nukliyeerka
Sababo la xiriira caabbinta sare ee SCC, godad iyo daxalka dillaaca, Sanicro 28 ayaa loo doortay kulaylka kuleyliyaha ee warshadaha tamarta nukliyeerka.
Biyaha badda iyo biyaha qaboojiyaha leh koloriin
Iska caabbinta sare ee daloolka iyo daxalka dillaaca ayaa ka dhigaya Sanicro 28 walxo aad ugu habboon tuubooyinka biyaha badda qaada iyo kulaylka qaboojiya biyaha badda. Tan waxaa lagu xaqiijiyay khibrad wax ku ool ah.
Sanicro 28 waxa uu beddelay nikkel alloys, CuNi, tuubooyinka bimetallic iyo tuubooyinka birta kaarboon ee dahaarka leh, kuwaas oo ku guuldareystay daxalka awgeed. Waxqabadka Sanicro 28 ayaa ahaa mid aad u wanaagsan.
Qaboojiyayaal kulaylka qaboojiyey biyaha badda iyo kulaylka ku shaqeeya biyaha qaboojinta koloriin-ku-dhalatada, Sanicro 28 waxay bixisaa iska caabbinta daxalka sare ee biyaha iyo dhexdhexaadiyaha la qaboojiyey labadaba.
Marka warshad biyaha badda lagu qaboojiyo la xiro, looma baahna in la daadiyo nidaamka tuubooyinka ama lagu nadiifiyo biyo cusub, waase haddii muddada xiritaanka ay ka gaaban tahay hal bil heerkulka biyuhuna uu ka hooseeyo 30°C (85°F) .
Birta aan daacin ee duplex 2507 ayaa ka adkeysi badan Sanicro 28 ee biyaha badda.
