S31803 yog ib lub qauv duplex steel hlau (tseem hu ua 2205) ua rau micrived sib npaug ntawm kwv yees li 50% austenite thiab 50% ferrite. Tus qauv no muab kev sib xyaw ua ke ntawm lub zog siab, tshwj xeeb tshaj tawm tsam chloride kev ntxhov siab corrosion), thiab Weldability zoo. Unrical tsis muaj yeeb nkab Stainless Hlau
yog dav siv nyob rau hauv kev sib zog ib puag ncig uas cov qauv qib kev kawm qib qis (piv txwv li 304/316) tsis txaus.
Cov Nta Tseem Ceeb
Lub zog siab:
Kwv yees li ob zaug ntxiv tau lub zog ntawm cov qauv Austenitic stainless hlau (piv txwv li 316L), tso cai rau txo cov phab ntsa tuab thiab txo qis nyiaj.
Zoo tshaj plaws corrosion:
Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-containing environments.
Tus nqi -}} Ua tau zoo:
Muaj kev ua yeeb yam - rau -}} {}}} Raws li alloys hauv ntau daim ntawv thov.
Zoo weldability:
Yuav muab welded siv cov kev sib txuam, tab sis kev kho mob yuav tsum tau ua los tswj cov Austenite {{m}} ferrite Tshuav.
