Material number · Europe · 2 designations # 1.4407 1.4407 is the material number of the grade also listed as GX5CrNiMo13-4. It is a material in the category Cast stainless steels. We list 2 designations recorded for this grade, in the standards DIN / EN and UNS. - ***Material no.* **1.4407**** - [*Category* **Cast stainless steels · 87 grades**](/categories/cast-stainless-steels "Category: Cast stainless steels · 87 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=aa2391c0-0109-4669-8d64-2a7b646682f2 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.4407.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN GX5CrNiMo13-4 This grade’s own name](/materials/din-en/gx5crnimo13-4 "DIN / EN GX5CrNiMo13-4") - [UNS J91550 This grade’s own name](/materials/uns/j91550 "UNS J91550") ## About Cast stainless steels Cast stainless steels are stainless-steel materials produced by casting, combining corrosion resistance with the ability to form complex component shapes. Their composition and mechanical behaviour vary by grade, and they are used for corrosion-resistant cast components such as pumps, valves and process equipment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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. ## 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.
