DIN / EN · Europe · 3 designations # L360MB L360MB is a material in the category Others, held under material number 1.0578. Its recorded composition includes C ≤ 0.16%, Si ≤ 0.45%, Cr ≤ 0.3%, Mn ≤ 1.6% and Ni ≤ 0.3%. We list 2 designations recorded for this grade, in the standards DIN / EN and AISI / SAE. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.0578**](/materials/material-no/1.0578 "Material no.: 1.0578") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=a52c9519-566c-491a-bd52-8d36ffe4b483&designation=b1622c24-ca57-45f8-ae8d-1bd6c415ce2a "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/l360mb.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN StE 360.7 TM This grade’s own name](/materials/din-en/ste-360-7-tm "DIN / EN StE 360.7 TM") ## About Others These are miscellaneous metallic alloys that do not fit a more specific material family and may be based on iron, nickel, cobalt, copper or other alloy systems. They are selected for applications requiring particular combinations of strength, hardness, toughness, wear resistance or resistance to demanding service conditions. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Where this grade also has a measured transformation point (Ac1, Ac3, Ar1, Ar3) on file, it is shown separately, in Physical & mechanical properties, and is never replaced by the predicted figures here — Ae (predicted, equilibrium) and Ac/Ar (measured, on heating or cooling) are different physical quantities and can differ by tens of degrees; a mismatch between the two is not an error in either. ## 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.
