c. Strain Hardening.
(1) General. The cold working of steel stresses it beyond its elastic limit and leaves a
residual strain. After the cold working, the steel has an increased yield stress. This process of raising
the yield stress is known as cold working. The amount of strain hardening is relative
to the amount of cold working. In normal roll forming, the cold working is nominal, the steel remains
ductile and it makes a modest improvement in the allowable stress of the section. Extensive cold
working of steel can cause it to loose its ductility and become brittle, but normally, this condition is not
associated with common roll formed products.
(2) Cold Reducing and Rerolling of Steel. Steel mills have the capability to cold reduce the
steel sheet to meet the specified thickness before shipment to the manufacturer. Some manufacturers
can reroll the steel sheet to again reduce the sheet thickness. Within the AISI Specification this is
known as Other Steel. This practice is allowed by the AISI Specification if the rerolled steel meets the
ductility criteria of the AISI Section A3.3. Therefore, the manufacturer is strain hardening the material.
