The most-used names for this grade.About Cold extrusion steels
Cold extrusion steels are engineering materials designed to be shaped into components by cold forming and extrusion. They combine the ductility needed for substantial plastic deformation with the strength and toughness required in cold-formed fasteners, automotive parts and other precision components.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition
6 elements on file · weight %What this alloy is
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.

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.

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 1.1, a shared category, and a published range for Mn / Si 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.
