Nov 09, 2013 · Annealing of Cold Rolled Steel. The cold rolling of steel is done at temperatures below the recrystallization temperature. During cold rolling process the reduction in thickness is due to plastic deformation which occurs by means of dislocation movement. Steel gets hardened because of the buildup of these dislocations.
C1018 STEEL-COLD ROLLED FLAT BAR - Metal SupermarketsSTEEL-COLD ROLLED. Cold rolling increases the strength and hardness and decreases ductility of steel by rolling it at ambient temperature (or below its recrystallization temperature). In addition to improvement of mechanical properties, the cold rolling produces steel plate/sheet of the desired physical dimensions.

GOST 17066 describes the technical specifications for thin-gauge, high-strength rolled steel with a thickness of 0.5-3.9 mm and a minimum width of 500 mm manufactured in sheets and coils. Rolled steel is produced with a strength of 295, 315, 345, 355 or 390. The shape and size tolerances of cold-rolled steel should also correspond to GOST 19904.

Module 2.2.1 Effect of Rolling and Annealing on Rolling is a common method of working a material. The as-received brass was initially cold rolled from a casting into a sheet then annealed. This is why the initial microstructure shows metal grains that are somewhat elongated in one direction (slide 8). Each grain is a single crystal area differentiated from its
