Hot rolled square steel bars offer high workability, which makes them easy to weld, form, cut, and machine. These characteristics make square steel bars a very desirable material for various industrial applications, such as welding, construction, repairs, and general fabrication.
Manufacturing hot rolled square steel bars involves passing steel through rollers to shape the metal to a specific thickness at temperatures exceeding steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be easily shaped and formed. This allows the steel to be drastically reduced in thickness with only single pass. Compared to cold rolled steel, hot rolled steel is not only easier to work with during and after the rolling process, it is also cheaper to produce.
Hot Rolled Square Bar Applications:
Hot rolled square steel bars will change shape and size during the cooling process, thus resulting in slightly rounded edges and corners. They are also characterized by a rough surface finish due to extreme temperature cooling process. Hot rolled square bars maintain excellent mechanical properties and is easy to fabricate using conventional methods, including hot forming and mild cold forming.
Square steel bars are used where heavy thickness, strength levels, and formability are required, which makes them an ideal choice for producing structural components. Also, hot rolled square steel bars can be easily welded and drilled. They are used in various industries and applications, including:
Automotive, Power Generation, Food Processing, Aerospace, Water Treatment, Chemical Processing, Oil and Gas, Marine, Medical, Construction, Outdoor Furniture
Advantages:
Hot rolled steel refers to a steel-rolling process in which flat steel is rolled at extremely high temperatures that exceed the recrystallization temperature, which makes it very malleable. Once heated and molded, hot rolled steel is cooled at room temperature. While this gives the finished product looser tolerances than the original material, it also makes the product free from internal stresses that may occur during heat-treatment processes such as quenching and work-hardening process. Finally, steel shrinks slightly as it cools and so there is less control over its final shape. Thus, hot rolled steel can vary in dimensional consistency and have rougher edges than cold rolled steel.
