DIN / EN · Europe · 2 designations # HCT600X HCT600X is a designation in DIN / EN for the material held under material number 1.0941, also listed as H340X. It is a material in the category Dual phase steels. We list 2 designations recorded for this grade, in the standards DIN / EN. - [*Material no.* **1.0941**](/materials/material-no/1.0941 "Material no.: 1.0941") - [*Category* **Dual phase steels · 4 grades**](/categories/dual-phase-steels "Category: Dual phase steels · 4 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=6b521ceb-b842-4625-be95-f75f00fc1545&designation=1adc5a34-d8bc-47fb-a34d-a1adf59597a3 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/hct600x.pdf "Datasheet as PDF") ## About Dual phase steels Dual phase steels are steels with a ferritic matrix containing a dispersed martensitic phase. This combination provides a balance of strength, ductility and formability, making them suitable for formed structural and safety components, especially in vehicle bodies. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 / Al 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.
