steel is pickled in acid to remove the mill scale and then oiled to keep it from rusting. The cost is somewhere in between that of regular hot rolled and cold rolled. Finally, in my experience, the more popular (to the steel yard) sizes of mild steel usually come in both cold and hot rolled. I buy hot rolled whenever I can for blacksmithing.

Cold finished steel is essentially hot rolled steel that has further processing. Cold finished steel, also known as cold rolled, is typically produced as turned bars or cold drawn bars. Cold drawing hot rolled bars is accomplished by pulling (drawing) a bar through a die which is smaller than the incoming hot rolled size.

Cold-rolled Full Hard. Full hard steel has been cold-reduced to a point where yield and tensile strength are nearly equal. This means that the steel is hard and strong and does not deform. Elongation is <2%, typically; the last operation is either a tandem cold reduction mill or a cold reversing mill. Hardness is typically at least RB85.

Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction. Cold rolled steel is then annealed to induce ductility in the cold rolled steel which is simply known as a Cold Rolled and Close Annealed. [19] Skin-rolling, also known as a skin-pass, involves the least amount of reduction: 0.5–1%.

Hot rolling vs. cold rolling. Before moving on to cold rolling, the metal is 'pickled', which means the scale formed by hot rolling is removed from the surface of the metal, otherwise it would interfere with the process. Cold rolling takes the hot rolled product and processes it further.

If hot rolled sheet is specified for a part that will be roll formed, you'll still get some added strength. But it won't match the strength you would have received if you started with standard cold rolled material. Size Limits. As we mentioned, steel sheet is only hot rolled up to a certain thickness. You can't buy 20 gauge hot rolled sheets.

For production of cold rolled steel usually two types of annealing processes are used. They are as follows. Soft annealing of steel – This type of annealing precipitation of cementite and pearlite to reduce the strength of the steel for facilitating the forming operation. Common temperature for this annealing ranges from 680 deg C to 780 deg C.

The first feature is size. Comparing to a hot rolled bar, which is formed (rolled) at high temperatures, a hot rolled bar will vary greatly in size, with a larger variance the bigger the diameter. Hot rolled bars can also have an oval or eggy-shape to it. Roundness on a cold finished bar will coincide with size, being half the size tolerance.
