About High-speed steels

High-speed steels are alloyed tool steels designed to retain hardness and cutting ability when tools heat up during high-speed machining. Their hot hardness and wear resistance make them suitable for cutting tools such as drills, milling cutters, taps and broaches.

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

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 1.3, a shared category, and a published range for Mo / Cr 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.
