About Low-temperature structural steels
Low-temperature structural steels are structural steels designed to retain toughness and reliable load-bearing performance in cold service. Their resistance to brittle fracture at low temperatures makes them suitable for structures, pressure-containing equipment and other components exposed to severe cold.
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 |
|---|---|
≤ 0.3 | |
≤ 0.35 | |
≤ 1.35 | |
≤ 0.03 | |
≤ 0.03 |
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

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.
