Super duplex 2507 yeeb nkabCov khoom siv kho tshuab muaj siab heev, vim lawv ua tau zoo dua li austenitic lossis ferritic hom stainless hlau. Vim yog cov ntsiab lus siab ntawm molybdenum, npib tsib xee thiab chromium, lawv kuj muaj ntau ntawm austenite stabilizing element nitrogen. Lub duplex microstructural theem, nrog nws kuj muaj zog thiab check super duplex welded hlab. Txawm li cas los xij, nws yog qhov tsis lees paub tias lub siab muaj peev xwm ntawm Super Duplex 2507 Seamless yeeb nkab yuav luag 20% siab dua li cov welded raj, thiab tus nqi kuj tseem siab dua.
