Superalloys for additive manufacturing and HIP

Our range of nickel-based superalloys has been extended by the addition of powders with extremely low levels of Oxygen and Nitrogen, making them especially suited for additive manufacturing and HIP (hot-isostatic pressing). These low levels are achieved through the use of vacuum melting as part of the gas atomization process.

1) This alloy resists a wide range of severely corrosive environments.

2) This alloy combines excellent fatigue resistance and rupture strength at high temperature.

3) This alloy combines corrosion resistance and high strength with outstanding weldability including resistance to post weld cracking.

4) This alloy also has good resistance to high-temperature corrosion and oxidation.

5) This alloy is used extensively in high-temperature applications.

Our program of nickel-based superalloys is now extended with powders with extremely low levels of Oxygen and Nitrogen, making them especially suited for additive manufacturing and HIP (hot-isostatic pressing). The high cleanness is achieved through our gas atomising process with melting under vacuum.
