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.

Chemical composition
5 elements on file · weight %What this alloy is
Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.
| Element | % by weight |
|---|---|
2.42–2.48 — | |
3.7–4.5 | |
2.9–3.3 | |
7.6–8.2 — | |
3.9–4.3 |
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.

Predicted transformation temperatures
Not enough recorded composition to predict a transformation temperature for this grade — missing: Mn, Si, Ni.
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.
