Typical use	Alloy 625 (UNS N06625) is a nickel-chromium-molybdenum alloy with an addition of niobium. The addition of molybdenum acts with the niobium to stiffen the alloy matrix, providing a high strength without a strengthening heat treatment. The alloy resists a wide range of corrosive environments and has a good resistance to pitting and crevice corrosion. Alloy 625 is used in chemical processing, aerospace and marine engineering oil & gas, pollution control equipment and nuclear reactors.
Weight Formula	Average Wall: (OD-WT) x WT x 0,0270 = Kg/m (all sizes in mm) Minimum Wall: (OD-WT) x WT x 0,0281 = Kg/m (all sizes in mm)
