ASTM A790 steel yeeb nkab yog dab tsi?
ASTM A790 UNS S32750 (Duplex 2507) yog super duplex stainless hlau uas muaj 25% chromium, 4% molybdenum thiab 7% npib tsib xee, nws muaj nyob rau hauv seamless thiab welded ferritic / austenitic stainless hlau kav.
2205 duplex stainless hlau yeeb nkab muaj cov cuab yeej zoo heev, corrosion kuj, thiab zoo weldability. Nws yog dav siv nyob rau hauv kev lag luam roj thiab roj, marine engineering, tshuaj lom neeg kev lag luam thiab lwm yam lag luam. Kev lag luam roj thiab roj siv hluav taws xob 2205 duplex stainless hlau kav los nteg ntau tshaj 850km ntawm cov roj thiab cov kav dej.
Feem ntau ntawm lawv yog 2205 duplex stainless hlau seamless steel kav (qee yam yog S31803 duplex stainless hlau kav thiab 2507 duplex stainless hlau kav); nyob rau hauv West-East Gas Transmission Project, vim yog qhov muaj zog heev ntawm cov pa nruab nrab, 2205 stainless hlau kav yog siv rau cov kav dej siab.
