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.

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.

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.
