UNS · United States · 2 designations # N08125 N08125 is a designation in UNS for the material held under material number Ni 8125, also listed as NiFe26Cr25Mo. It is a material in the category Others. We list 2 designations recorded for this grade, in the standards DIN / EN and UNS. - [*Material no.* **Ni 8125**](/materials/material-no/ni-8125 "Material no.: Ni 8125") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=4c8fc428-5da0-4a2b-a0ff-a77706da559d&designation=3d1f3fc8-47af-4a09-8aed-4c0f8324d193 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/uns/n08125.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN NiFe26Cr25Mo This grade’s own name](/materials/din-en/nife26cr25mo "DIN / EN NiFe26Cr25Mo") ## About Others These are miscellaneous metallic alloys that do not fit a more specific material family and may be based on iron, nickel, cobalt, copper or other alloy systems. They are selected for applications requiring particular combinations of strength, hardness, toughness, wear resistance or resistance to demanding service conditions. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here. ## 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?
