Even though cold rolled steel has many similarities to hot rolled
steel, there are several key differences that separate the two
processes. Within production, cold rolled steel requires increased
processing over hot rolled. This production takes place in cold
reduction mills, where the material is cooled (at room temperature)
followed by annealing and/or tempers rolling. This process will
produce steel with closer dimensional tolerances and a wider range
of surface finishes.
Conversely, the hot rolling process takes less time and in turn
does not cost as much as cold rolling. Hot rolled steel is
typically formed above 1700° F, which is above the steel’s
recrystallization temperature. This allows the steel to be shaped
and formed easily and formed into much larger sizes.
Carbon Steel Rod
A low carbon steel with a medium manganese content, 1018 has good case hardening properties and excellent machinability. Suitable for shafting and for other applications that do not require the greater strength of high carbon and alloy steels.
Carbon steel has high strength, good plasticity and toughness. It
belongs to the comprehensive mechanical properties of good steel,
with very broad, mainly used to make the load of the larger small
cross-section conditioning large normalizing and stress smaller
parts, and of the request is not high intensity of surface
quenching parts, such as the spindle, crank shaft, shaft, gear,
worm, keys, pins, etc. Water quenching has a tendency to form
cracks, and parts with complex shapes should be hardened in hot
water or oil.
