Hot Rolled Sheets

Product Details:

Hot Rolled Sheets are steel sheets produced by rolling steel at high temperatures. This process involves heating the steel above its recrystallization temperature and then passing it through rollers to achieve the desired thickness and dimensions.

Properties:

• Material:

  • Mild Steel: Mild steel, also known as low-carbon steel, is used for its good weldability, machinability, and affordability. It contains a low amount of carbon (typically less than 0.25%), which makes it ductile and malleable.

• Manufacturing Process:

  • Hot Rolling: The HR sheet is produced by heating steel billets to a high temperature (above the steel's recrystallization temperature) and then rolling them into sheets. This process reduces the thickness of the steel and shapes it into flat sheets. The hot rolling process is performed at high temperatures, typically between 1,700°F and 2,200°F (926°C to 1,204°C), which allows the steel to be easily formed and shaped.

• Surface Finish:

  • Finish: Hot rolled sheets often have a rougher surface finish compared to cold-rolled sheets. The surface can exhibit a scaled or mill scale appearance due to the high-temperature processing. However, the surface can be treated or further processed to achieve a smoother finish if required.

• Thickness and Dimensions:

  • Thickness: Mild steel HR sheets are available in a range of thicknesses, typically from 1.5 mm to 12 mm or more, depending on the application requirements.
  • Width and Length: The width and length of HR sheets can vary widely. Standard widths are commonly available in the range of 1000 mm to 2000 mm, and lengths can be customized based on specific needs.

• Mechanical Properties:

  • Strength: Mild steel HR sheets offer good tensile strength and can be used in a variety of structural and industrial applications. The strength may vary based on the specific grade and thickness of the sheet.
  • Ductility and Formability: The hot rolling process enhances the ductility and formability of the steel, allowing it to be easily shaped and fabricated.

Applications:

• Construction:

  • Used in structural components such as beams, columns, and supports. HR sheets are commonly used in construction for both residential and commercial buildings.

• Automotive:

  • Employed in the automotive industry for manufacturing parts such as body panels, frames, and chassis components due to their strength and formability.

• Manufacturing:

  • Used in various manufacturing processes to produce components and products, including machinery, equipment, and metal products.

• Fabrication:

  • Utilized in metal fabrication for creating custom parts and structures. The sheets are often cut, welded, and formed to meet specific design requirements.

• Industrial Applications:

  • Used in industrial applications where a strong and cost-effective material is required. This includes applications like tanks, pipelines, and heavy-duty equipment.
