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.
