2205 Duplex Stainless Hlau Yeeb Nkab: Qhov ntom ntom, lub cev muaj zog

Yog tias koj tab tom nrhiav qhov siab - lub zog, corrosion- cov kav hlau tsis muaj zog rau qhov xav tau ib puag ncig, 2205 duplex stainless hlau yeeb nkab yog ib qho ntawm cov khoom siv dav tshaj plaws hauv cov haujlwm niaj hnub no. Paub txog nws qhov sib npaug duplex microstructure, 2205 ua ke cov kev tiv thaiv corrosion ntawm austenitic stainless hlau nrog lub zog ntawm ferritic steel - ua rau nws muaj nqi - siv tau zoo rau cov kav dej siab, marine systems, thiab kev ua tshuaj lom neeg.
 

2205 Duplex Stainless hlau yeeb nkab yog dab tsi?

2205 duplex stainless hlau sib raug rau UNS S31803 / UNS S32205, muaj 50% ferrite + 50% austenite microstructure. Cov qauv no muab cov khoom siv zog ntau dua thiab txhim kho kev tiv thaiv rau chloride kev nyuaj siab corrosion cracking piv rau 304 thiab 316 stainless hlau kav.
