  • Difference Between Hot and Cold Rolled Steel

    2014-9-11u2002·u2002Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The 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.

  • Bending Basics: The fundamentals of heavy bending

    2014-1-2u2002·u2002Nonetheless, compared with cold forming, hot forming allows a much greater degree of formability and reduced tonnage requirements, which makes it an attractive alternative when press tonnage capacity is an issue. The press brake may not be able to form a plate cold, but it can form it hot. Like anything else, hot forming has its limitations.

    2018-4-12u2002·u2002these products from hot rolled steel sections. Normally, the yield strength of steel sheets used in cold-formed sections is at least 280 N/mm2, although there is a trend to use steels of higher strengths, and sometimes as low as 230 N/mm2. Manufacturers of cold formed steel sections purchase steel coils of 1.0 to 1.25 m width,

  • Quality Prediction of Strip in Finishing Rolling Process ...

    2021-5-21u2002·u2002The experimental data in this paper comes from a 1580 mm hot strip finishing line of a steel company. The production line consists of 7 units. After 5~7 passes of rough rolling, we can get intermediate billet of 25~60 mm thick, which can be sent to the finishing mill after the hot coil box, flying shear, and dephosphorization box.

  • Minimum versus recommended inside bend radius

    2015-4-1u2002·u2002The minimum inside bend radius is even larger when bending with the grain. In steel between 0.5 and 0.8 in. thick, grade 350 and 400 may have a minimum bend radius of 2.5 times the material thickness when transverse bending, while longitudinal bending may require a minimum bend radius that's 3.75 times the material thickness (see Figure 1 ).
