The most-used names for this grade.About Phosphorus alloyed steels
Phosphorus-alloyed steels are steels in which phosphorus is used as a deliberate alloying element. They are characterised by phosphorus-assisted strength and machinability, and are used for components where these properties support efficient manufacturing and service performance.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition
6 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 |
|---|---|
≤ 0.05 | |
≤ 0.4 | |
≤ 0.6 | |
0.08 — | |
0.025 | |
≥ 0.015 |
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: 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.
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.
