Cold finished steel also has a smoother and more fragile finish when compared to hot rolled meaning that transportation and storage of the metal type must happen with extra care.

Hot rolled sheet metal. For other forms such as bars or plates materials are sectioned and packaged. Hot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate. It is measured by its thickness gauge. When galvanized it is also regularly used in applications where corrosion resistance is a necessity.

Continuous rolling gives the desired final shape a metal sheet 3 mm and upwards or profile. Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. Typically cold finished metal is used in parts that require crimping bending or swaging. C1008 1010 hr steel sheet astm a1011 a569 hot rolled steel sheets are the most economical steel sheets available for a wide variety of applications hr steel sheets are easy to weld form and drill and has a slight grainy surface.

High strength and highly formable hr steel sheet and plate is also easy to drill form and weld. The steel cools. 3 5 rs 42 000 metric ton. Steels of different grades can be produced as hot rolled or cold rolled.

The starting material is usually large pieces of metal like semi finished casting products such as slabs blooms and billets.

Customers 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.

This keeps the market price of hot rolled steel lower. As the metal is shaped at the. Often used in general fabrication where finish is not critical. Automotive panels tool boxes hoppers drip pans fuel tanks trailer siding roofing etc.

After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening. Hot rolled steel properties. The white hot strands of steel are pushed through the rollers at high speeds. Thicknesses beyond this point are considered to be plate.
