Dab tsi yog cov khoom tseem ceeb ntawm 2507?
2507 Duplex stainless hlau UNS S32750 DIN / EN 1.4410 F53 SAF 2507
Nws yog ferritic-austenitic (duplex) stainless hlau uas sib txuas cov khoom muaj txiaj ntsig zoo tshaj plaws ntawm ntau cov ferritic steels thiab austenitic steels. Txij li cov hlau muaj cov ntsiab lus chromium thiab molybdenum siab, nws muaj peev xwm tiv taus pitting corrosion, crevice corrosion thiab uniform corrosion. Ob txoj kev microstructure xyuas kom meej tias cov hlau muaj kev tiv thaiv kev ntxhov siab corrosion thiab muaj zog txhua yam.
Stainless hlau yog siv rau hauv kev lag luam roj thiab roj; offshore Shipotian roj platforms (kub exchanger raj, dej kho thiab dej system, hluav taws xob tiv thaiv systems, sprinkler systems, dej stabilization systems; petrochemical khoom; desalination (desalination) cov cuab yeej (thiab cov khoom siv nyob rau hauv high-pressure kav, seawater kav); mechanical thiab Cov khoom siv uas yuav tsum tau muaj zog thiab siab corrosion kuj; combustion (khoom siv) roj purification khoom.
