VDM® Alloy 825
VDM® Alloy 825 is a titanium-stabilized fully austenitic nickel-iron-chromium alloy with additions of copper and molybdenum. It is used in the oil and gas industry and in a wide variety of chemical processes.
- High resistance to chloride-induced stress corrosion
- Good resistance to chloride-induced pitting and crevice corrosion
- Good resistance to oxidizing and non-oxidizing hot acids
- Good toughness, even under continuous operation, at both room and elevated temperatures, up to approximately 550 °C (1.020 °F)
- Approval for pressure vessels with wall temperatures up to 450 °C (842 °F) acc. to VdTÜV and 538 °C (1,000 °F) for Section VIII Division 1 vessels acc. to ASME.
