UNS · United States · 3 designations # N08031 N08031 is a designation in UNS for the material held under material number 1.4562, also listed as X1NiCrMoCu32-28-7. It is a material in the category Stainless steels. We list 3 designations recorded for this grade, in the standards DIN / EN and UNS. - [*Material no.* **1.4562**](/materials/material-no/1.4562 "Material no.: 1.4562") - [*Category* **Stainless steels · 468 grades**](/categories/stainless-steels "Category: Stainless steels · 468 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=778bd470-b7e0-47c5-abf3-1f593ead0016&designation=bd52ac9f-f08c-4a22-9309-a4adbe41c7a3 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/uns/n08031.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X1NiCrMoCu32-28-7 This grade’s own name](/materials/din-en/x1nicrmocu32-28-7 "DIN / EN X1NiCrMoCu32-28-7") - [UNS S38031 This grade’s own name](/materials/uns/s38031 "UNS S38031") ## About Stainless steels Stainless steels are corrosion-resistant alloy steels whose chromium content promotes a protective passive surface film. They are used for equipment, structures and components exposed to moisture, chemicals or hygienic service, with different alloy compositions selected for corrosion resistance, strength, formability or weldability. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 3 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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?
