Super Duplex 2507 Stainless Hlau Bar

UNS S32750

UNS S32750, feem ntau hu ua Super Duplex 2507, zoo ib yam li UNS S31803 Duplex. Qhov sib txawv ntawm ob yog cov ntsiab lus ntawm chromium thiab nitrogen siab dua nyob rau hauv Super Duplex Qib uas nyob rau hauv lem tsim muaj zog corrosion kuj zoo li lub neej ntev. Super Duplex yog tsim los ntawm 24% mus rau 26% chromium, 6% mus rau 8% nickel, 3% molybdenum, thiab 1.2% manganese, nrog rau qhov sib npaug yog hlau. Tsis tas li ntawd pom nyob rau hauv Super Duplex yog cov kab ntawm carbon, phosphorus, sulfur, silicon, nitrogen, thiab tooj liab. Cov txiaj ntsig muaj xws li: weldability zoo thiab ua haujlwm tau zoo, qib siab ntawm thermal conductivity thiab qis coefficient ntawm thermal expansion, siab tiv thaiv corrosion, qaug zog, siab tsis kam rau pitting thiab crevice corrosion, siab tsis kam rau kev ntxhov siab corrosion cracking (tshwj xeeb tshaj yog chloride stress corrosion cracking), siab zog nqus, siab zog, thiab yaig. Qhov tseem ceeb, Duplex alloys yog kev sib haum xeeb; muaj qee qhov ferritic kev nyuaj siab corrosion cracking tsis kam thiab ntau ntawm superior formability ntawm cov austenitic stainless hlau alloys, ntau tus nqi zoo tshaj cov siab nickel alloys.
