Hot Rolled Steel Sheet

Hot Rolled Steel Sheet is a steel product produced by high temperature hot roll rolling. Among them, A36 and A1011 hot-rolled steel sheets are ideal for most processing technologies. With carbon steel sheet as the substrate, in addition to carbon steel sheet, galvanized sheet, and stainless steel sheet can also be hot rolled. Hot rolling is a process to improve performance. Hot rolled steel sheet is mainly used to make structural parts such as automobile beams, cross beams, drive shafts, and automobile chassis parts. Wanzhi Steel provides hot rolled plates, hot rolled steel coils, and hot rolled steel strips with a length of 4m-12m, a width of 0.6-3.0m, and a thickness of 0.1mm-300mm.

What is a hot rolled steel sheet?

Hot rolled steel is rolled above the metal recrystallization temperature, usually at 1,700°F, and has good plasticity and low deformation resistance, making it easy to roll.

What is the difference between hot rolled and cold rolled sheets?

Simply put, cold rolling is an extra step compared to hot rolling.

In detail, cold rolled steel is essentially hot rolled steel that has been rolled by cooling it at room temperature and annealing or tempering. Cold rolled steel has relatively tighter dimensional tolerances and a smoother surface.

A36 Hot Rolled Steel Plate

A36 hot rolled steel plate has a rough surface, bluish gray color, blunt edges, and imprecise dimensions throughout its length. It is a low carbon steel, commonly referred to as mild steel, that is durable. Common applications include base plates, brackets, gussets, and trailer manufacturing. ASTM A36 / A36M-08 is the standard specification for carbon structural steel.

For material with a thickness of ¼” and larger, consider the A1011 hot rolled steel plate.

A1011 Hot rolled steel plate

A1011 hot rolled steel plate is ideal for most processing techniques. It has a smooth surface and a bluish gray color also. In addition, A1011 is considered a commercial-grade alloy material. Common applications include base plates, brackets, gussets, sheathing, and decorative items. ASTM A1011 is a Standard Specification for Steel, Plate, Strip, Hot-Rolled, Carbon, Structural, High-Strength Low Alloy, High-Strength Low Alloy with Improved Formability and Ultra-High Strength.

Features

• Low energy consumption and no obvious work hardening.
• Large ingots and large reduction rolling are usually used, with fast production rhythm and large output.
• The cast structure is transformed into the processed structure through hot rolling to improve the plasticity of the material.
• The properties of the plate after rolling are anisotropic, such as obvious differences in longitudinal, transverse, and high-direction properties.

How is it produced?

The production process of hot-rolled steel plates mainly includes heating, rolling, cooling, and other processes.

The picture below records the entire production process of hot rolled steel in a relatively complete manner, you can use it as a reference.

Process drawing 1.

Based on our years of experience, the production steps can be summarized into the following three steps:

• Heating: The billet is heated above the recrystallization temperature to improve its processing properties.
• Rolling: After multiple rolling processes, the heated billet is rolled into a steel plate of the required thickness.
• Cooling: The rolled steel plate needs to be cooled to eliminate internal stress and improve the performance of the material.

Uses

The specifications of hot-rolled steel plates are diverse and can be customized according to customer needs. It has a wide range of uses, including but not limited to the following aspects:

• Building and structural materials: such as building steel, bridges, shipbuilding, etc.
• Mechanical equipment: used to manufacture large machinery and pressure vessels, etc.
• Automobile manufacturing: Hot-rolled steel plates are widely used in car bodies and frame structures, especially thicker parts.
• Other fields: They can also be used to make containers, welded pipes, steel structures, and pipelines for transporting oil and natural gas.

Which is more expensive, hot rolled or cold rolled steel?

As mentioned above, cold rolling is a process based on hot rolling to obtain steel plates with more accurate size, smoother surface, easier forming, and better performance. Therefore, the cost of cold rolled steel panels is higher than hot rolled steel panels.

Is hot rolled steel mild steel?

Hot rolled mild steel is a flat steel product produced by hot-rolling process, which has strength and durability. It is low carbon steel. Hot rolled steel is formed by the metal rolling process, in which steel is pressed at a temperature above its recrystallization threshold.
