DIN / EN · Europe · 3 designations # X6NiCrNbCe32-27 X6NiCrNbCe32-27 is a designation in DIN / EN for the material held under material number 1.4877, also listed as X5NiCrNbCe32-27. It is a material in the category Heat resistant steels. We list 3 designations recorded for this grade, in the standards DIN / EN and UNS. - [*Material no.* **1.4877**](/materials/material-no/1.4877 "Material no.: 1.4877") - [*Category* **Heat resistant steels · 64 grades**](/categories/heat-resistant-steels "Category: Heat resistant steels · 64 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=6c55b4ac-7d8e-43cf-85a9-575a2c1dfaed&designation=7cfc906e-1d66-4d80-bdbc-9da07f4505a9 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/x6nicrnbce32-27.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS S33228 This grade’s own name](/materials/uns/s33228 "UNS S33228") ## About Heat resistant steels Heat resistant steels are alloyed materials designed to retain useful mechanical properties and resist oxidation or scaling during service at elevated temperatures. They are used for components in furnaces, boilers, heat exchangers and power-generation equipment exposed to hot gases or sustained heat. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 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. ## Properties by condition 1 conditions · 1 values By delivery state**Solution annealed** source `steelnumber` | Delivery state | HB | |---|---| | Solution annealed | 223 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Looking for this grade under another name?
