Kev Piav Qhia Luv:

904L Cov Hlau Stainless Hlau. UNS N08904, feem ntau hu ua 904L, yog cov hlau tsis muaj carbon ntau thiab cov hlau austenitic uas siv dav hauv cov ntawv thov uas cov khoom xeb ntawm AISI 316L thiab AISI 317L tsis txaus. Cov hlau austenitic no tiv taus kev tawm tsam los ntawm cov kua qaub sulfuric, phosphoric acid thiab acetic acid. Nws tiv taus pitting hauv cov kua chloride tsis muaj zog. Nws tiv taus kev ntxhov siab corrosion cracking hauv qee cov chlorides kub zoo dua li cov nickel austenites qis dua. Cov hlau no muaj kev ua tau zoo thiab weldability. Cov khoom siv no muaj nyob rau hauv txhua tus qauv zoo li ASTM thiab EN, txawm li cas los xij nrog qee qhov sib txawv. Kev tsim qauv siab txog li 370 ° C suav nrog hauv ASME II.
