Cold Finished steel is Hot Rolled steel that has had further cold working done to it. Cold Finished steel, also known as Cold Rolled, is typically produced as Cold Drawn (CD) Turned & Polished (TP), or Turned Ground & Polished (TGP). Cold drawing hot rolled bars is accomplished by pulling (drawing) a bar through a carbide die which is smaller than the incoming hot rolled size. Turning hot roll bars is a cold machining process that removes (peels) the surface to improve dimensional control and removes superficial elements that may be detrimental to the parts being produced. We also offer grinding, which can further tighten the dimensional tolerances of the bars.

All Cold Finished steel products have several benefits over Hot Rolled steel.

THE SURFACE FINISH

Hot rolled steel can have “mill scale” on the surface whereas Cold Finished steel will have a bright shiny appearance.

CONSISTENCY OF DIAMETER AND STRAIGHTNESS TOLERANCES

An example would be using a 1″ bar in 1018 Hot Roll would yield a diameter variance of + / – .009″. That same diameter in a Cold Finished condition would provide a +0″ / -.002″ variance in diameter.

INCREASED MECHANICAL PROPERTIES

You can expect higher yield and tensile strengths with Cold Finished, which can help reduce additional thermal heat treating requirements on the finished parts in some cases.

MACHINABILITY

Finally, an added advantage of using Cold Finished vs Hot Rolled steel is that the machinability can improve by as much as 20% in some cases, which saves on tool life, increases production speeds, and improves surface finish of parts.
