In short, hot rolled steel is processed at the mill at high temperatures and that''s it. On the other hand, cold rolled steel is processed as hot roll, but once it has cooled to room temperature, it received additional processing for different benefits. Generally speaking, hot roll steel has a rougher surface, wider tolerances, and lower cost.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
Some Things to be aware of: 1) Hot Rolled Steel products are NOT a consistent blueish color. This is particularly true with hot rolled sheet, over the surface of which t he color varies dramatically, more blue at the edges, more grey in the center of the sheet. 2) The shapes available in hot rolled steels are availble in 12ft, 20ft, and sometimes 40ft lengths, so check with your supplier.
After hotrolled sheet is pickled, leveled, and edgetrimmed, our coldrolling mill is capable of reducing the steel''s thickness to as thin as inches and as thick as .085 inches.

Hot rolling is often the cheapest way to form steel because additional steps that cold rolled steel requires, such as annealing, are avoided. A bluish iron oxide layer, known as mill scale, forms on the surface of hot rolled steel due to the elevated temperature.
Cold Rolled Tempers. Cold working of copper and copper alloys, by rolling or other methods, will increase both tensile strength and yield strength in a very predictable manner. Most copper alloys are produced to a series of coldrolled tempers with a tensile strength range unique to .
Sep 11, 2014· Customers often ask us about the differences between hot rolled steel and cold rolled are some fundamental differences between these two types of differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
Hotrolled vs Coldrolled Steels. There are two distinct forms of plate and sheet steel available for the various alloys of carbon steel: hot rolled and cold rolled. Hot rolled steel has a course, grainy surface with dark streaks. This grainy texture is the result of removing the deep scale during the pickling process.
