Nyob rau hauv duplex stainless hlau (DSS), lub austenite theem thiab ferrite theem account rau ib nrab ntawm cov khoom tov qauv, thiab muaj ob-theem qauv yam ntxwv.Nws tsis tsuas yog khaws cov yam ntxwv ntawm ferritic stainless hlau, xws li loj thermal conductivity, me me linear expansion coefficient, tsis kam rau pitting corrosion thiab crevice corrosion, thiab chloride stress corrosion, tab sis kuj muaj zoo toughness, tsis tshua muaj nkig hloov kub thiab kuj rau intergranular corrosion. ntawm austenitic stainless hlau.Nrog rau kev ua tau zoo thiab lwm yam zoo, nws yog dav siv hauv petrochemical, luam ntawv thiab dyeing, marine engineering, zaub mov kev lag luam thiab ntawv ua lag luam.
Nrog rau qhov sib txawv ntawm qhov loj ntawm cov cuab yeej siv niaj hnub no thiab txo cov nqi tsim khoom, qee cov khoom loj feem ntau yog tsim los ntawm overlaying duplex stainless hlau corrosion-resistant khaubncaws sab nraud povtseg ntawm low-alloy steel substrates.
Strip electroslag surfacing txheej txheem yog dav siv hauv kev tsim khoom vim nws qhov ruaj khov vuam zoo, qib siab ntawm automation, thiab kev ua haujlwm siab.
