Material number · Europe · 2 designations # 1.4860 1.4860 is the material number of the grade also listed as X16NiCr30-20. It is a material in the category Resistance heating alloys. We list 2 designations recorded for this grade, in the standards DIN / EN. - ***Material no.* **1.4860**** - [*Category* **Resistance heating alloys · 9 grades**](/categories/resistance-heating-alloys "Category: Resistance heating alloys · 9 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=916023a8-afcb-4372-8325-1cd8071eedab "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.4860.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN NiCr 30 20 This grade’s own name](/materials/din-en/nicr-30-20 "DIN / EN NiCr 30 20") ## About Resistance heating alloys Resistance heating alloys are metallic alloys designed to generate heat when an electric current passes through them. They combine electrical resistance with stability during prolonged heating, making them suitable for heating elements in furnaces, ovens and industrial equipment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 designations · 1 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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: Mo. ## 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?
