Alloy 825 / Incoloy 825 is the forerunner of many of the Molybdenum containing nickel iron chromium alloys which have seen service over the past century.
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.
