VDM® Alloy 625

VDM® Alloy 625 is a nickel-chromium-molybdenum-niobium alloy with excellent resistance to a variety of corrosive media. In the soft annealed condition (grade 1; annealed at 950 to 1,050 °C (1,742 to 1,922 °F)), the alloy is used for wet corrosion applications and is approved by TÜV for pressure vessels in a temperature range from -196 to 450 °C (- 320 to 842 °F). For high temperature applications above 600 °C (1,112 °F), the solution annealed variant (grade 2; annealed at 1,080 to 1,160 °C (1,976 to 2,120 °F)) is generally used. The strength of VDM® Alloy 625 can be enhanced by heat treatment.
The soft annealed version of VDM® Alloy 625 (grade 1) is used in the oil and gas industry, the chemical process industry, marine engineering and environmental engineering. Typical applications include:

  • Equipment for the production of super phosphoric acid
  • Plants for the treatment of radioactive waste
  • Production pipe systems and linings of risers in oil production
  • Offshore industry and seawater exposed equipment
  • Seawater piping in shipbuilding
  • Stress corrosion cracking resistant compensators
  • Furnace linings

The solution annealed variant of VDM® Alloy 625 (grade 2) is used for high-temperature applications up to 1,000 °C (1,832 °F), acc. to ASME Code for Pressure Vessels. Typical applications include:

  • Flaring systems in refineries and offshore platforms
  • Recuperators and compensators for hot exhaust gases

VDM® FM 625 is used as a matching filler metal for corrosion-resistant coatings of less resistant steels (overlay welding). Typical applications include:

  • Components in the oil and gas extraction
  • Superheater tubes in waste incineration plants
