VDM 625 (Nicrofer 6020 hMo) is a nickel-chromium-molybdenum-niobium alloy with excellent resistance to a variety of corrosive media. In the soft annealed condition (grade 1), 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 840 °F). For high temperature applications above 600 °C (1110 °F), the solution annealed variant (grade 2) is generally used. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on forming, heat treating, machining, and joining. Filing Code: Ni-760.
