About Free cutting steels
Free-cutting steels are steels formulated to machine readily and produce manageable chips during cutting. Their machinability makes them suitable for turned, drilled and threaded components produced in high volumes, including small precision parts and fasteners.
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 |
|---|---|
0.32–0.39 | |
0.15–0.4 | |
0.9–1.4 | |
≤ 0.06 | |
0.15–0.25 |
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.

The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred.
Predicted transformation temperatures
Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Cr, Mo.
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.
