Hot rolled steel strip

Cold-rolled steel sheet is an abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold plate, sometimes mistakenly written as cold-rolled plate. Cold plate is made of ordinary carbon structural steel hot-rolled steel strip, after further cold-rolled to a thickness of less than 4mm steel. Because of rolling at room temperature, does not produce scale, so cold plate surface quality, high dimensional accuracy, combined with the annealing treatment, its mechanical properties and process properties are superior to hot-rolled steel sheet, in many areas, especially Appliance manufacturing, it has been gradually replaced by hot-rolled steel sheet. The equipment is able to reach domestic first-rate level.

I know you are very interested in learning about what hot rolled steel is used for. But guess what Buzz readers, it is actually used for some interesting applications. Like we discussed in the Hot Rolled Steel: How it is Made post, hot rolled steel is the most basic form of steel a mill produces. Hot rolled dry sheets and coil are a darker grey than most other steel types and have a silvery blue, almost purple strip along both sides.

Today, I'll cover some of the unique properties of this steel product, along with a few of its most common applications. Strip steel is known for having tighter thickness tolerances than cold rolled steel. Prior to rolling, hot rolled strip steel is pickled to remove surface impurities and ensure the final product will have a clean, uniform finish.
