About Unalloyed structural steels

Unalloyed structural steels include all low-carbon steels in which the iron companions do not exceed specified minimum values. The yield strength, formability and weldability are the decisive factors for their use. They are soft, pliable, tough and stretchy, but cannot be hardened by heat treatment.

This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Indicativetaken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering.

Withdrawndesignation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Superseded bythe current name this withdrawn designation was replaced by — the same grade under its present designation, the one to order by today.

What this alloy is

Iron — the balance, never listed by a standard — 97.8 %Mn — 1.4 %Cu — 0.6 %C — 0.2 %Traces & impurities · 0.1 %

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

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.

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.

2 further values are held for this grade under a condition the source did not name — a bound with no quantity attached. They are withheld rather than shown against a guessed condition.

Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ.

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 / Cu 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.
