STS44
STS44 is a grade designated under KS. Its recorded composition includes C 0.8–0.9%, Si ≤ 0.25%, V 0.1–0.25%, Cr ≤ 0.2% and Mn ≤ 0.3%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include HB 207.

Chemical composition
7 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 |
|---|---|
0.8–0.9 | |
≤ 0.25 | |
≤ 0.3 | |
≤ 0.03 | |
≤ 0.03 | |
≤ 0.2 | |
0.1–0.25 |
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, 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.
