About High-strength multi-phase steels

High-strength multi-phase steels are iron-based materials with multiple microstructural constituents designed to provide high strength with useful ductility. They are used for load-bearing and crash-relevant components where weight reduction, structural performance and energy absorption are important.

This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

What this alloy is

Iron — the balance, never listed by a standard — 97.3 %Mn — 1.8 %Si — 0.5 %C — 0.2 %Traces & impurities · 0.2 %

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Physical & mechanical properties

Density7,85g/cm³Exact

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.
