Ua ntej, cov hlau muaj qhov sib xyaw ua ke ob lub microstructure thiab tau teeb tsa hauv qhov sib piv 50: 50 (austenite thiab ferrite). Lub zog siab tuaj yeem tau txais los ntawm nws sab ferritic. Thib ob, chemistry ntawm Super Duplex Stainless Steel F53 Hex Bar suav nrog ntau lub ntsiab lus uas yog - 25% chromium, 4% molybdenum, nrog rau 7% npib tsib xee. Tag nrho cov ntsiab lus pab ua kom lub zog tawm los ntawm cov hlau.
Lub zog tawm los ntawm cov hlau no tawm mus txog li 570 MPa. Lub zog ib sab, A240 S32750 Super Duplex Phaj yog ib qho hlau uas muaj qhov zoo tshaj plaws tiv thaiv corrosion thiab corrosion los ntawm pitting. Qhov tsis kam rau pitting tuaj yeem lees paub los ntawm qhov siab heev PREN lossis Pitting Resistance Equivalent tau txais los ntawm cov hlau. Tus qhab nia PREN ntawm UNS S32750 F53 Square Bar muaj nuj nqis ntawm qhov ntau tshaj 40, yog li ua pov thawj tias cov hlau tiag tiag muaj kev tiv thaiv siab rau pitting corrosion. ASTM A240 UNS S32750 Phaj yog cov hlau tsis muaj steel hlau uas muaj kev tiv thaiv zoo heev rau chloride ion kev ntxhov siab cuam tshuam txog kev tawg. Ntxiv mus, ASTM A240 gr S32750 Sheet nthuav tawm cov thermal conductivity ntau dua, nrog rau nws muaj qis coefficient lossis tus nqi ntawm thermal expansion. Nrog rau qhov muaj cov yam ntxwv zoo li no, Duplex UNS S32750 Coil tuaj yeem ua tau zoo hauv cov haujlwm uas muaj cov khoom siv tshuaj, petrochemical, thiab cov khoom siv hauv hiav txwv lossis brine.
