Alloy 825 (UNS N08825) is a nickel chromium alloy ine molybdenum yakawedzerwa, pamwe nemhangura.Iyo ine yakanakisa kuramba kudzikisira uye oxidizing acids, kusagadzikana ngura kutsemuka, uye ngura yemunharaunda, senge gomba uye crevice corrosion.
Alloy 825 inonyanya kukodzera kupikisa sulfuric acid uye phosphoric acid.
Iine ductility yakanaka uye inogona kuumbwa nyore nyore nenzira dzose dzakajairika.
