ABOUT ALLOY 825 / INCOLOY 825

As the forerunner of many of the Molybdenum containing nickel iron chromium alloys Incoloy Alloy 825 still plays a significant role in heat exchangers for chemical processing,pollution control equipment , oil well and gas gathering pipes – even as clad steel pipe - where resistance to stress cracking or general corrosion to a range of reducing or oxidising acids is required.
