Hot Rolled Steel Flat Rectangle Bar
A hot-rolled steel rectangle bar undergoes a heating process during its production. Manufacturers use a heat range above a steel’s recrystallization temperature of 400 to 700°C. This heating process makes the steel malleable, allowing it to be shaped into various products, including rectangular flat bars.
During the hot roll process, a billet metal slab is heated, compressed, and wound into coiled rolls. Once cooled, the rolls are cut into specific shapes, like a hot-rolled flat bar.
The heating process changes the metal’s structure on a molecular level, forming dendrites that later transform into organized grains. These grains and their directional grain flow contribute to the strength and durability of hot-rolled steel bars.
In contrast to cold-rolled steel, which undergoes an additional re-rolling process, hot-rolled steel is faster to produce and more cost-effective. The additional cold-rolling step adds strain hardening but also extends production time.
Benefits and Applications of Hot Rolled Steel Flat Bar?
Hot rolled steel flat bars offer a number of advantages to project managers and builders:
- Cost-Effectiveness in Manufacturing and Fabrication: A hot-rolled steel bar requires less processing, so it offers lower costs than cold-rolled steel, making it ideal for large-scale projects.
- Easy to Form and Shape: Because it has been processed at elevated temperatures, it is easier to form and shape in the ensuing processing operations.
- Durability and Versatility in Structural Projects: As the steel cools, its structures are normalized, resulting in minimal internal stress. This makes it highly durable and versatile for use in various construction projects.
Because hot rolled steel bars naturally contract after cooling, this can result in slight warping, varied thickness, and a scaled finish. These features make hot-rolled steel flat bars an excellent choice for projects where precision is less critical, but strength and cost-effectiveness are key factors. As a result, hot-rolled steel is widely used in industries like:
- Agricultural machinery
- Automotive components
- Construction materials
- Railroad tracks and railcar parts
Available Sizes and Dimensions for Rectangular Flat Bar (Hot Rolled)
Alcobra Metals offers a wide range of hot-rolled steel rectangular bars in various sizes and dimensions for different projects. Our selection includes T304 and T316 stainless steel flat bars, providing options for environments requiring higher corrosion resistance and durability levels.
- T304 Stainless Steel: The most commonly used stainless steel grade, T304, offers corrosion resistance due to its high nickel and chromium content. This versatile grade is widely available for everyday components and equipment.
- T316 Stainless Steel: T316 stainless steel includes a higher level of molybdenum. It is commonly used for marine environments because it’s more corrosion-resistant than T304. Common applications include marine equipment, seafood production facilities, refineries, and chemical transportation.
