Alloy 825 / W 2.4858 / UNS N08825
Alloy 825 is an austenitic nickel-iron-chrome alloy with the addition of molybdenum, copper and titanium. It was developed to offer extraordinary corrosion resistance in both oxidation and reduction environments. This alloy is able to withstand chloride stress corrosion on crevices and pits.
Due to the addition of titanium, Alloy 825 is stabilised to prevent sensibilisation in its welded state, meaning it is able to withstand intercrystalline attacks after exposure to temperatures in a range that would cause sensibilisation for unstabilised stainless steel sensors. The manufacturing process for Alloy 825 is typical for alloys containing nickel, that result in materials being easily formable and weldable using a variety of techniques.
