DIN / EN · Europe · 2 designations # NiCr22Mo7Cu NiCr22Mo7Cu is a material in the category [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys"), held under material number 2.4619. Its recorded composition includes C ≤ 0.015%, Cr 21–23.5%, Fe 18–21%, Co ≤ 5% and Mo 6–8%. We list one designation recorded for this grade, in the standard UNS. Its recorded density is 7.85 g/cm³. - [*Material no.* **2.4619**](/materials/material-no/2.4619 "Material no.: 2.4619") - [*Category* **Nickel and cobalt alloys · 87 grades**](/categories/nickel-and-cobalt-alloys "Category: Nickel and cobalt alloys · 87 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=384bb99c-ee24-4a4c-a3e2-a7f0a2f36efe&designation=4a95b465-959b-4b18-a16a-25db58d03b20 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/nicr22mo7cu.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS N06985 This grade’s own name · 3 grades on that route](/materials/uns/n06985 "UNS N06985") ## About Nickel and cobalt alloys Nickel and cobalt alloys are metallic materials whose properties are developed through nickel-, cobalt-, or combined alloying systems. They are characterised by strong resistance to corrosion, oxidation, wear, and loss of strength at elevated temperatures, making them suitable for turbine components, chemical-processing equipment, and other demanding high-temperature applications. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 designations · 2 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni. ## Physical & mechanical properties Density 7,85 g/cm³ Exact An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 2.4, a shared category, and a published range for Ni / Cr that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
