Nickel Alloy 825 may be a nickel-iron-chromium alloy with additions of Mo, copper, and metal. The alloys chemical composition is meant to supply exceptional resistance to several corrosive environments. The nickel content is spare for resistance to chloride-ion stress-corrosion cracking. The nickel, in conjunction with the Mo and copper, conjointly provides outstanding resistance to reducing environments, like those containing sulphuric and chemical element acids. The Mo conjointly aids resistance to roughness and crevice corrosion. and also the metal addition serves to stabilize the alloy – following acceptable heat treatment – against sensitization to inter-granular corrosion.
