What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
Round steel three processing methods are more common, should be very wide surface. Hot rolled round steel, used in construction and general hardware parts processing is very common.
Cold drawn round steel (don't know, you mean can not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
The main differences are in mechanical properties. I don't know very well how to make round steel, I can't compare it. Forged round steel is expected to be used in the processing of some special performance requirements.
