What is 2.4856? Nickel Alloys
2.4856 is the Werkstoff number for a nickel-based alloy most commonly known as Inconel 625. The Werstoff designation was developed by the German standards body DIN, with the term Werkstoff translating approximately to ‘material’.
Inconel 625 was launched in 1964 following development by Special Metals Corporation. Inconel 625 achieves reasonably high strength through the addition of molybdenum and niobium to the nickel-chromium base, but nowhere as high as Inconel 718. However, due to the high level of chromium and molybdenum it is corrosion resistant in the most aggressive of environments. It is particularly resistant to pitting and crevice corrosion with a pitting resistance equivalent number (PREN) of over 45.
