5. Dab tsi yog qhov zoo ntawm 2205 duplex stainless hlau?
Tshwj kev txiav txim siab corrosion tsis kam:
Reseds pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking (e .} {{4 4}}
Siab zog-rau-qhov hnyav piv:
Muab ~ × cov txiaj ntsig lub zog ntawm cov nqaj hlau tsis sib xws, ua kom lub tshuab tsim khoom muag thiab cov nyiaj txo qis.
Zoo Weldability (nrog cov txuj ci kom zoo):
Tuaj yeem welded siv cov fillers nyiam er2209, txawm tias kev tswj thermal yog qhov tseem ceeb los tswj xyuas cov theem sib npaug thiab zam tsis txhob muaj theem li)} {{4}
Durability thiab kev txij nkawm tsawg:
Kev tawm tsam nkees thiab tawg hauv daim ntawv thov kev ntxhov siab muaj kev ntxhov siab, txo lub neej kav.
Raug nqi rau cov mob hnyav:
Thaum pib kim dua cov qauv stainless hlau, nws muab lub sijhawm ntev txuag hauv kev xeb lossis siab tshaj plaws ib puag ncig.
Ductanced ductility thiab tawv tawv:
Ua ke cov ductility ntawm Austenite nrog lub zog ntawm ferrite, haum rau dynamic thauj khoom tshwm sim scenarios .
