DIN / EN · Europe · 2 designations # H380LAD HX380LAD is a material in the category [Higher strength steels](/categories/higher-strength-steels "Higher strength steels"), held under material number 1.0934. Its recorded composition includes C ≤ 0.11%, Si ≤ 0.5%, Ti ≤ 0.15%, Mn ≤ 1.4% and Nb ≤ 0.09%. We list one designation recorded for this grade, in the standard DIN / EN. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.0934**](/materials/material-no/1.0934 "Material no.: 1.0934") - [*Category* **Higher strength steels · 20 grades**](/categories/higher-strength-steels "Category: Higher strength steels · 20 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c0b8fb4e-756f-49fc-ab1b-8db0817899c9&designation=dd5c33a9-f474-44df-a457-a94dfbb63868 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/h380lad.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN HX380LAD This grade’s own name](/materials/din-en/hx380lad "DIN / EN HX380LAD") ## About Higher strength steels Higher strength steels are structural materials designed to carry greater loads than conventional structural steels while retaining useful ductility. They are used for load-bearing structures and components where higher strength can support efficient material use and durable fabricated designs. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 designations · 1 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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, 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 1.0, a shared category, and a published range for Mn / Si 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.
