Super Duplex Steel F53
UNS S32750yog ib tug super duplex stainless hlau, alloy 2507 muaj 25% chromium, 4% molybdenum thiab 7% npib tsib xee. Nws yog feem ntau siv tau cov khoom siv lub teeb 2507 kom ua tiav tib lub zog tsim raws li cov nickel alloys tuab, zoo heev txo cov nqi tsim khoom tag nrho. F53 stainless hlau yog tsuas yog siv nyob rau hauv ib puag ncig corrosive heev.
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm
Mixed Microstructure:Qhov sib npaug 50: 50 austenitic thiab ferritic grain qauv muab cov neeg kho tshuab siab ua ke nrog zoo heev ductility.
Stress Corrosion Cracking Resistance:Kev tiv thaiv zoo rau chloride-induced stress corrosion cracking (SCC) nyob rau hauv hnyav marine thiab tshuaj ua daim ntaub ntawv.
Pitting thiab Crevice Protection:High Pitting Resistance Tus lej sib npaug (PREN ntau dua 41) ua kom muaj kev nyab xeeb nyob rau hauv siab -chloride, qhov chaw dej hiav txwv sov.
High Thermal Efficiency:Tsawg thermal expansion coefficient thiab siab thermal conductivity piv rau cov qauv austenitic stainless hlau.
Kev Tiv Thaiv Kev Kub Ntxhov: Pom zoo rau daim ntawv thov txog li 600℃F (316 degree) los tiv thaiv microstructural embrittlement.
