Nickel 3D-printing with materials such as Inconel, Hastelloy and waspaloy

The nickel-based alloy Alloy 625 exhibits very good corrosion resistance, especially to pitting and crevice corrosion. The material also reacts insensitively to many acids. Due to the addition of molybdenum and niobium, good mechanical properties are achieved even without downstream heat treatment. In the solution-annealed condition, the material can be used for temperature ranges above 600 °C. Typical applications are in the chemical, offshore and nuclear industries. Thanks to its excellent weldability, additive manufacturing can be used to realize a wide range of products.
