| Application areas | 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, sea water 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). Typical applications include: Flaring systems in refineries and offshore platforms, recuperators and compensators for hot exhaust gases | |
| Corrosion properties | The corrosion resistance depends on the processing and heat treatment of the material. The conventionally produced VDM® Alloy 625 usually has excellent corrosion resistance to a variety of corrosive media in the soft annealed condition (grade 1): Excellent resistance to pitting and crevice corrosion in chloride-containing media, virtual immunity to chloride-induced stress corrosion cracking, high resistance to corrosion attack by mineral acids such as nitric, phosphoric, sulfuric, and hydrochloric acid; as well as by concentrated alkalis and organic acids, both under oxidizing and reducing conditions, very good resistance in seawater and brackish water, even at elevated temperatures, high resistance to intergranular corrosion after welding and heat treatment, high resistance to erosion corrosion, in the solution annealed variant VDM® Alloy 625 (grade 2) is usually highly resistant to many corrosive gas atmospheres: Good resistance to carburizing and scaling under static and cyclic conditions, resistance to nitriding. | |
| Other | VDM® Alloy 625 has a cubic face centered lattice. | |
