‘2.4856’ is the Werkstoff number for a nickel-based alloy, most commonly known as Inconel 625. The Werkstoff designation was developed by the German standards body DIN, with the term Werkstoff translating approximately to ‘material’.
2.4856, also referred to as Inconel 625, was launched in 1964 following development by Special Metals Corporation. It achieves reasonably high strength through the addition of molybdenum and niobium to the nickel-chromium base, but nowhere as high as 2.4668 (Inconel 718).
Due to the high level of chromium and molybdenum, 2.4856 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. It can be supplied in hot worked and annealed conditions.
In terms of applications, it is perfectly suited to the most demanding conditions, from sub-zero to extremely high-temperature environments. Particularly useful in situations where oxidation resistance and avoidance of pitting are required. In the annealed condition, this Inconel alloy is fully austenitic and suitable for machining. It provides excellent corrosion resistance in a wide variety of severely corrosive environments due to its high alloy content. With nearly 60% nickel composition, it is virtually immune from stress corrosion cracking.
2.4856 is also non-magnetic and able to operate over a wide temperature range, from cryogenic temperatures up to 980degC. This supports applications in jet engines, heat exchangers, furnace hardware and chemical plant equipment.
