    Difference Between Hot and Cold Rolled Steel Metal

    Sep 11, 2014 · Hot Rolled Steel Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot Rolled Black Steel Pipe Manufacturers and Suppliers Hot rolled black steel pipe is one of the simplest and most durable ways to join pipes together and steel pipes can simply be welded together with MIG (metal inert gas), TIG (tungsten inert gas or SMAW (stick metal arc) welding. Before welding two pipes together, avoid any gaps between the two pipes.

    Hot Rolled Vs. Cold Rolled Coils - EU-Metal

    As the hot rolled coil is reconfigured by applying heat on it and then cooling it, the end finish is usually more unusual and rough. In addition to that hot rolled coil is also less durable than cold-rolled steel. Moreover, hot-rolled coil tends to have more carbon content which is nearly 0.29 percent, which is a concern for forging. Hot sell Cold Rolled Steel Sheet and Coil - Steel Exporter Hot sell Cold Rolled Steel Sheet and Coil Cold Rolled Steel is a mill product made with a high degree of gauge accuracy and uniformity of physical characteristics. The smooth deoxidized matte finish gives an excellent base for paint, lacquer and enamel.
