Incoloy alloy 825 is a nickel-iron-chromium alloy with copper, titanium and molybdenum added. There is ample nickel content for resistance to chloride-ion stress-corrosion cracking. The nickel, combined with molybdenum and copper, also results in great resistance to reducing environments such as the ones consisting of phosphoric and sulfuric acids. It is used in applications like acid production and nuclear fuel reprocessing. Incoloy alloy 825 suppliers and Incoloy alloy 825 manufacturers like Supreme Engineering Limited play a key role in the production of alloys.
The molybdenum also aids resistance to crevice corrosion and pitting. This alloy's chromium content gives out resistance to different oxidizing substances like nitric acid, oxidizing salt and nitrates. With the addition of titanium and an apt heat treatment, the alloy gets stabilised against sensitization to inter-granular corrosion. It is also used in applications like pollution control, pickling operations and oil and gas recovery.
