DIN / EN · Europe · 4 designations # NiMo28Fe NiMo28Fe5 is a material in the category [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys"), held under material number Ni 1001. Its recorded composition includes C ≤ 0.08%, Fe 4–7%, Co ≤ 2.5%, Ni ≥ 55% and Mo 26–30%. We list 3 designations recorded for this grade, in the standards DIN / EN and UNS. Its recorded density is 7.85 g/cm³. - [*Material no.* **Ni 1001**](/materials/material-no/ni-1001 "Material no.: Ni 1001") - [*Category* **Nickel and cobalt alloys · 87 grades**](/categories/nickel-and-cobalt-alloys "Category: Nickel and cobalt alloys · 87 grades") - *Designations* **4** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=0c4a8f5e-3d49-459c-9841-6c68ecfd3ebe&designation=661831e7-f648-4654-9547-bb95858b6f0e "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/nimo28fe.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN NiMo28Fe5 This grade’s own name](/materials/din-en/nimo28fe5 "DIN / EN NiMo28Fe5") - [UNS N10001 This grade’s own name · 4 grades on that route](/materials/uns/n10001 "UNS N10001") ## 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 4 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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. ## Looking for this grade under another name?
