Alloy 625 / 2.4856
Alloy 625 is a low carbon (0.03%) nickel-chromium-molybdenum-niobium alloy which has excellent corrosion resistance to a wide range of corrosive media. Alloy 625 is normally supplied in annealed condition for wet corrosion applications and is TÜV-approved for pressure vessels in the temperature range from -196°C to 450°C. In annealed condition (grade 1) Alloy625 is characterized by:
