Zithunzi za S32760
S32760 (F55), X2CrNiMoCuWN 25.7.4, German muyezo 1.4501, mphamvu yamphamvu ndi kukana dzimbiri, makamaka ntchito pokonza mankhwala, petrochemical ndi subsea zipangizo.Imakhala ndi kukana kwamphamvu kwa chloride corrosion, high matenthedwe madutsidwe ndi otsika matenthedwe kukulitsa coefficient.Kuchuluka kwa chromium, molybdenum ndi nayitrogeni, kumakhala ndi mphamvu yolimbana ndi maenje, kuwononga ming'alu ndi dzimbiri.
Alloy S32760 ndi chitsulo chosapanga dzimbiri chopangidwa ndi duplex chomwe chimaperekedwa munjira yotentha yogwirira ntchito komanso yankho lokhazikika.Monga chitsulo chosapanga dzimbiri cha duplex, chimaphatikiza zinthu zofunika zazitsulo za austenitic ndi ferritic.Kuchuluka kwa chromium, molybdenum ndi nayitrojeni kumapangitsa Pitting Resistance Equivalent Number (PREN)> 40, kupereka mphamvu zowomba kwambiri komanso zowononga zitsulo zosapanga dzimbiri za austenitic ndi duplex pafupifupi pafupifupi zida zonse zowononga, komanso kutentha koopsa kwambiri Chenjezo loposa 50°C.Mtundu wa fomula ya PREN umaphatikizanso W ngati zotsatira zabwino pakukana kukana kwa pitting.
Zimapereka mphamvu zapamwamba kuposa zitsulo zosapanga dzimbiri za austenitic ndi 22% Cr duplex ndipo zalembedwa ku NACE MR 0175 pa ntchito yowawasa ndi ASME pakugwiritsa ntchito zotengera zokakamiza.
