DIN / EN · Europe · 5 designations # GX9Ni5 GX9Ni5 is a designation in DIN / EN for the material held under material number 1.5681, also listed as GS-10 Ni 19. It is a material in the category Low-temperature structural steels. We list 5 designations recorded for this grade, in the standards DIN / EN, UNS and AISI / SAE. - [*Material no.* **1.5681**](/materials/material-no/1.5681 "Material no.: 1.5681") - [*Category* **Low-temperature structural steels · 55 grades**](/categories/low-temperature-structural-steels "Category: Low-temperature structural steels · 55 grades") - *Designations* **5** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=6dbaeb43-7fe8-4a8f-8f68-0f3a8f48bf3f&designation=964e3edb-d81e-4588-879b-1481fd6a4889 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/gx9ni5.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS J41501 This grade’s own name](/materials/uns/j41501 "UNS J41501") - [AISI / SAE E2512 This grade’s own name](/materials/aisi-sae/e2512 "AISI / SAE E2512") ## 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 5 designations · 3 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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: Cr, 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 1.5, a shared category, and a published range for Ni / 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.
