Alloy 825 (UNS N08825) yog nickel chromium alloy nrog molybdenum ntxiv, nrog rau tooj liab.Nws muaj kev tiv thaiv zoo heev los txo thiab oxidizing acids, kev ntxhov siab corrosion tawg, thiab hauv zos corrosion, xws li pitting thiab crevice corrosion.
Alloy 825 yog tshwj xeeb tshaj yog haum rau tsis kam mus rau sulfuric acid thiab phosphoric acid.
Nws muaj ductility zoo thiab tuaj yeem tsim tau yooj yim los ntawm txhua txoj hauv kev.
