Mu duplex Stainless simbi (DSS), iyo austenite chikamu uye ferrite chikamu account yeinenge hafu yeiyo yakasimba mhinduro chimiro, uye ine maviri-chikamu chimiro chechimiro. Iyo haingochengete chete hunhu hweferritic Stainless simbi, senge hombe yekupisa yekupisa, diki mutsara wekuwedzera coefficient, kuramba pitting corrosion uye crevice corrosion, uye chloride stress corrosion, asiwo ine kuoma kwakanaka, yakaderera brittle shanduko tembiricha uye kuramba kune intergranular corrosion. ye austenitic simbi isina tsvina. Nekuita kwakanaka uye zvimwe zvakanakira, inoshandiswa zvakanyanya mu petrochemical, kudhinda uye dhayi, marine engineering, indasitiri yechikafu uye maindasitiri ekugadzira mapepa.
Nemaitiro ekuwedzera saizi yemidziyo yemazuva ano yemaindasitiri uye kudzikisira mitengo yekugadzira, zvimwe zvinhu zvakakura zvinogadzirwa nekufukidza duplex simbi isina corrosion-resistant layers pane yakaderera-alloy simbi substrates.
Strip electroslag surfacing process inoshandiswa zvakanyanya mukugadzira nekuda kwekugadzikana kwayo welding mhando, yakakwirira dhigirii otomatiki, uye yakakwirira kugadzirwa.

Tafura 2 GDS-2209&GXS-E330 yakaiswa simbi kuumbwa
Tafura 3 GDS-2209&GXS-E330 kukotama uye corrosion kuramba bvunzo

Munda application ye strip sufacing welding
Iyo duplex Stainless Stainless simbi strip zvigadzirwa zvakagadziridzwa nekambani yedu (strip GDS-2209 ine GXS-E330 flux) ine yakanakisa welding workability uye yemuviri nemakemikari zvivakwa, izvo zvinogona kusangana nezvinodiwa zvekugadzira nekugadzira. Kugamuchirwa kubvunza uye kutenga.
