The most-used names for this grade.About High-strength steels
High-strength steels are steels designed to carry high loads while resisting deformation. They are used for load-bearing structures, vehicles and machinery where strength, durability and reduced material weight are important.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition
8 elements on file · weight %What this alloy is
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
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 1.8, 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.
