ST12 cold rolled steel is essentially hot rolled steel that has been processed further.
Once hot rolled steel has cooled, it is then rolled to achieve more
exact dimensions and better surface qualities.
Cold rolled steel sheet(CR steel sheet)is essentially hot rolled
steel that has been processed further
Cold 'rolled' steel plate is often used to describe a range of
finishing processes—though, technically, 'cold rolled' applies only
to sheets that undergo compression between rollers. Things like
bars or tubes are 'drawn,' not rolled. Other cold finishing
processes include turning, grinding and polishing—each of which is
used to modify existing hot rolled stock into more refined
products.
ST12 cold rolled steel coil can often be identified by the following characteristics
1.Cold rolled steel has better, more finished surfaces with closer
tolerances
2.Smooth surfaces that are often oily to the touch in CR steel
sheet
3.Bars are true and square, and often have well-defined edges and
corners
4.Tubes have better concentric uniformity and straightness,made
from cold rolled material.
5.Cold rolled steel coil with better surface characteristics than
hot rolled steel, it's no surprise that cold rolled steel is often
used for more technically precise applications or where aesthetics
are important. But, due to the additional processing for cold
finished products, they come at a higher price.
In terms of their physical characteristics, cold worked steels are
typically harder and stronger than standard hot rolled steels. This
is because cold rolled steel finishing essentially creates a
work-hardened product. It's worth noting that these additional
treatments can also create internal stresses within the material.
In other words, when fabricating cold-worked steel—whether cutting,
grinding or welding it—this can release tensions and lead to
unpredictable warping.
