ASTM A928 yog tus qauv kev qhia tshwj xeeb rau ferritic / austenitic (duplex) stainless hlau kav rau hluav taws xob fusion vuam (EFW) nrog kev sib ntxiv ntawm cov hlau muab tub lim. UNS S31803 yog hais txog qib tshwj xeeb hauv tus qauv no, hu ua duplex 2205 stainless hlau yeeb nkab.
GNEE, raws li tus kws tshaj lij exporter ntawm duplex stainless hlau kav, khoom siv S31803 duplex stainless hlau kav nrog lub zog siab, zoo toughness, zoo heev corrosion kuj, tshwj xeeb tshaj yog tsis kam mus rau chloride kev nyuaj siab corrosion. Nws muaj qhov zoo oxidation tsis kam ntawm qhov kub thiab txias, tab sis nws yooj yim rau embrittlement thaum raug rau 370-540 degree lossis siab dua 300 degree rau lub sijhawm ntev. Nws muaj kev ua haujlwm vuam zoo heev thiab tuaj yeem hloov mus rau ntau txoj kev vuam thiab txheej txheem.
