Hot rolled round bar is a strong, tough, ductile, formable and weldable steel material that can be used for numerous types of applications. It also provides a rougher surface and can be easily shaped and formed. HR steel round bar stock is generally easy to drill and form while maintaining excellent mechanical properties. It is also characterized by its unique radius corners, compared to the sharp corners of cold rolled steel. It also maintains very good mechanical properties and is easy to fabricate.

What is Hot Rolled ASTM A36 Round Bar?
A36 is a low carbon steel that maintains less than a 0.3% carbon content by weight. The low carbon content within A36 allows it to be easily machined, formed and welded, which allows it to be used for a wide range of applications. However, since hot rolled ASTM A36 round bar does not contain large amounts of chromium and nickel it only provides average corrosion resistance. Some of the industries that regularly utilize A36 hot rolled steel, include:- Bridge construction
- Automotive
- Construction
- Heavy equipment
- Oil & gas
Hot Rolled ASTM A36 Round Bar vs 1018 Hot Rolled Steel in California
Since A36 and 1018 represent the two most popular steel grades within the metal industry it is important to point out their key differences. These disparities allow for a wide range of applicable uses for each metal grade. The main differences in each grade come down to the overall metal qualities and the advantages that they represent for each specific application.For example, 1018 is a mild low carbon steel that provides good ductility, toughness and strength qualities, it can also be easily welded through a variety of processes. This allows it to be used for heavy-duty hydraulic pumps and shafts.
Contrarily, A36 steel is less expensive than 1018 with similar, but less striking finish and machinability characteristics. A36 can also be easily welded, drilled, punched, tapped or machined, which makes it an excellent overall value when it comes to steel grades. Due to its significant cost advantages, A36 steel is commonly utilized for heavy duty construction and equipment applications.
Differences Between Cold Rolled & Hot Rolled Steel Round Bar
Even though cold rolled steel has many similarities to hot rolled steel, there are several key differences that separate the two processes. Within production, cold rolled steel requires increased processing over hot rolled. This production takes place in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.Conversely, the hot rolling process takes less time and in turn does not cost as much as cold rolling. Hot rolled steel is typically formed above 1700° F, which is above the steel’s recrystallization temperature. This allows the steel to be shaped and formed easily and formed into much larger sizes.
