HRC

作成者: 杉本 周平｜2025.07.09
Hot Rolled Coil (HRC) refers to steel that has been rolled at high temperatures, typically above 1,700°F (927°C), which is above the recrystallization temperature of steel. At this temperature, the steel is easier to form and shape, and it can be produced in much larger sizes. After being rolled, the steel is then coiled into large rolls for transportation and further processing.


Characteristics of HRC

  • Less Expensive: HRC is generally less expensive than cold-rolled coil because it involves fewer processing steps.
  • Wider Tolerances: Due to the high temperatures involved in its production, HRC has wider dimensional and shape tolerances compared to cold-rolled steel. This means its thickness, width, and flatness are not as precise.
  • Ductile and Malleable: HRC is very ductile and malleable, making it easy to work with and form into various shapes. It's less prone to fracturing during bending or welding.
  • Good for Structural Applications: Its strength and formability make it ideal for structural components, frames, and general fabrication where precise dimensions and a smooth surface finish are not critical.
