Hot Rolled Steel Bar
Hot rolled steel bars are obtained by taking raw steel, heating it to higher temperatures, and then rolling it into bars. These bars are commonly used for industrial, engineering and construction applications. Hot rolled steel bar is available in a variety of sizes, shapes, and alloys. Each of these various sizes, shapes,and alloys have specific safety, strength, and durability characteristics. Steel bars can range from small tool steel bar stock to larger structural shaped beams and road plates.
Hot rolled steel bars are distinguished from cold rolled steel bars in that the shape is less precise, often leaving rough surfaces and edges. The process of hot rolling also reduces the amount of flexibility in a piece of steel and makes it stronger. Hot rolled steel bars, however, are much easier to manufacture and are often less expensive than cold rolled steel bars.
Generally speaking, hot rolled steel bars are thicker and have higher tensile strength due to the higher temperature and pressure they experience. This results in an increased resistance to tears and increased strength of the bar itself. Hot rolled steel bars can be found in many different shapes including round, square, flat, and hexagonal.
The hot rolled steel bar is typically produced in long lengths, and depending on the steel grade will also determine the diameter that these bars come in. Typical diameters for hot rolled steel bars range from 10mm to 150mm.
The process of hot rolling steel bars can be done with a few different types of equipment. The first type of hot rolling machine is the bar mill, which works by heating a raw steel bar to a temperature of around 850 degrees Celsius. The steel is placed between two rollers which move in opposite directions in order to reduce the raw bar’s diameter to the required size.
Another type of hot rolling machine is the wire drawing machine, which is used to create high strength products from wire bars. These products are then cut and finished with a lathe in order to meet the customer’s specifications.
Hot rolled steel bars are generally cheaper than cold rolled steel bars and can be shipped far easier due to their reduced dimensional weight. Additionally, hot rolled steel bars are easier to work with and are less likely to buckle or bend in applications where angles need to be precise. In addition, hot rolled steel bars offer superior resistance to corrosion over cold rolled steel Bars.
When considering the grade of hot rolled steel bar, it is important to choose a product that meets or exceeds the specifications and requirements of the application. Different types of steel bar can be purchased in order to meet specific needs. Steel bar grades can range from low carbon steel bar to alloy steel bar, tool steel bar, and much more.
In conclusion, hot rolled steel bars are an ideal resource for a wide variety of applications and can be purchased in numerous grades and sizes. Due to their lower costs, stronger construction and corrosion resistance, hot rolled steel bars are preferred in many applications and are becoming increasingly more popular with global metal trading companies.
