DIN / EN · Europe · 3 designations # 26CrMo4 26CrMo4 is a designation in DIN / EN for the material held under material number 1.7219, also listed as 26CrMo4-2. It is a material in the category Low-temperature structural steels. We list 3 designations recorded for this grade, in the standards DIN / EN and UNS. - [*Material no.* **1.7219**](/materials/material-no/1.7219 "Material no.: 1.7219") - [*Category* **Low-temperature structural steels · 55 grades**](/categories/low-temperature-structural-steels "Category: Low-temperature structural steels · 55 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=94e0fbb8-36ac-4cbd-8762-c3b24b5c903c&designation=6d758953-0996-4f15-be20-97b0c48056d9 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/26crmo4.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 26CrMo4-2 This grade’s own name](/materials/din-en/26crmo4-2 "DIN / EN 26CrMo4-2") - [UNS K13047 This grade’s own name · 2 grades on that route](/materials/uns/k13047 "UNS K13047") ## About Low-temperature structural steels Low-temperature structural steels are structural steels designed to retain toughness and reliable load-bearing performance in cold service. Their resistance to brittle fracture at low temperatures makes them suitable for structures, pressure-containing equipment and other components exposed to severe cold. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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: Ni. ## 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 1.7, a shared category, and a published range for Cr / Mn 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.
