Material number · Europe · 34 designations # 1.4884 1.4884 is the material number of the grade also listed as X6CrNiSi18-13-4. It is a material in the category Others. We list 34 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, SAE AMS and ČSN. - ***Material no.* **1.4884**** - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **34** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=3e894c37-6716-493c-9bf0-20eaecad9ec8 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.4884.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X6CrNiSi18-13-4 This grade’s own name](/materials/din-en/x6crnisi18-13-4 "DIN / EN X6CrNiSi18-13-4") ## 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 34 designations · 6 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.4, a shared category, and a published range for Cr / Ni 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.
