Flat Steel Bar Common Specifications

Cold rolled coil is a Flat Steel Bar, usually called rolling hard roll, cold rolling caused by continuous cold deformation caused by hard rolling strength, hardness, toughness index decreased, so stamping performance will deteriorate, can only be used Simple deformation of the parts.

The Flat Steel Bar sheet is made of hot-rolled sheet at room temperature, although the steel sheet is heated during the processing process, although it is cold rolling. As a result of hot rolling through continuous cold deformation of the cold rolling, the mechanical properties are relatively poor, the hardness is too high. Must be annealed to restore its mechanical properties, no annealing is called rolling hard roll. Rolling rolls are generally used for products that do not require bending or stretching.

Flat Steel Bar is usually seen in the box, from the steel when it has been a good start. Applicable to most of the manufacturing industry on the market, the common specifications are: 0.7-3.0mm. Material ST12, ST13, ST14, ST15, ST16, ST17 and so on. Because from the steel out, the mechanical group control is relatively fine, out of the Flat Steel Bar is more accurate, so the general customer in the board is not required to use the case of Flat Steel Bar, which is the so-called box. But there are also some manufacturers or manufacturers with board specifications required, such as a wider 1780 or narrower. Longer or shorter, this time, you need cold rolled rolls. The cold rolled coil is like the tape we see in our daily life, and the cold rolled steel strip is rolled up and is called cold rolled coil. The CRC can be dimensioned according to the customer's requirements. It is more convenient to use.
