## 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.

What this alloy is

Fe Mn Si C

Iron — the balance, never listed by a standard — 98.2 % Mn — 1.2 % Si — 0.4 % C — 0.2 % Traces & impurities · 0.1 %

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

| Element | % by weight |
|---|---|
| C | ≤ 0.18 |
| Si | 0.15–0.55 |
| Mn | 0.8–1.6 |
| P | ≤ 0.035 |
| S | ≤ 0.035 |

Carbon Silicon Manganese Phosphorus Sulfur

0.01 % 0.1 % 1 % 10 % 100 %

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.

| Element | As published source text, verbatim | Min% by weight | Max% by weight | Bound |
|---|---|---|---|---|
| C | max 0.18 | — | 0.180 | Max |
| Si | 0.15 - 0.55 | 0.150 | 0.550 | Range |
| P | max 0.035 | — | 0.035 | Max |
| S | max 0.035 | — | 0.035 | Max |
| Mn | 0.8 - 1.6 | 0.800 | 1.600 | Range |

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.
