VDM® Powder 625 contains low amounts of oxygen of up to 0.03%.. 1 = The chemical analysis may differ slightly in some elements in other specifications and contain additional elements
- Corrosion Resistance
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 as 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
