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.
| Element | % by weight |
|---|---|
≤ 0.15 | |
≤ 0.5 | |
≤ 0.6 | |
≤ 0.04 | |
≤ 0.03 | |
4–6 | |
0.4–0.6 | |
≤ 0.6 |
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
This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here.
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.
