Material Characteristics

Alloy 699 XA is a nickel-chromium-aluminium alloy that exhibits excellent corrosion resistance. With a good weldability and its unique resistance against metal dusting – a special kind of high-temperature corrosion – the material is perfectly suitable for applications in the petrochemical industry like synthesis gas processes for the production of hydrogen, ammonia and methanol and the cooling of synthesis gas in the production of e-fuels. Combined with the advantages of Additive Manufacturing VDM Alloy 699 can be an enabler for demanding Power2X applications.

  1. The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
  2. Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
