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
steel type for normal building construction where shop and field welding is to be used. Although not recommended for low temperature service, these steels are widely used in compression members of bridges and similar structures and other applications where the possibility of brittle fracture is remote.

COLD-ROLLED STEEL. As you might suspect, the manufacturing process behind cold-rolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hot-rolled steel, cold-rolled steel has a nearly 20% increase in strength through the use of strain hardening.
Hot rolled steel and cold rolled steel are made using similar processing methods, but they have different qualities. hot rolled material 20crnimo steel bars For sheet metal, rolled steel is spun into coils and left to cool. For other forms, such as bars or plates, materials are sectioned and packaged. Steel shrinks slightly as it cools. Since hot rolled steel is cooled after hot rolled material 20crnimo steel bars
Standard AS/NZS 3679.1 Structural Steel Hot Rolled Bars and Sections. Grade Availability 300PLUS® Steel is the standard grade manufactured by OneSteel for hot rolled Structural Steel Sections for Australia. 300PLUS® Steel for hot rolled products is produced to exceed the minimum requirements of AS/NZS 3679.1 grade 300.
Hot rolled steel actually reconfigures itself during the cooling process, giving the finished product looser tolerances than the original material and when compared to cold rolled steel products. Hot rolled steel is more malleable, allowing it to be forced into a variety of different shapes.

Steel Bars 1-2 Cold Finished Carbon Bars Cold Finished Bars are produced from Special Bar Quality Hot Rolled Bars by cold drawing, turning or grinding or by a combination of these methods. The cross sectional area of the hot rolled bar is cold reduced, resulting in accurate size, smooth surface, increased mechanical properties and machinability.
RIVA ACCIAIO Catalogue - Updated - November, 2013 Page 5 of 20 Hot Rolled Round Steel Bars Quality Conditions SURFACE DEFECTS Defects are allowed up to a depth 0,8 % of the diameter or of the section side, with min. 0,3 mm and max 0,6 mm conforming with the following standards:
In general, forging produces more hot work through the thickness of the bar that rolling will. At least, many will believe it does. Depending on the size of the bar, there are some rolled bars produced by continuous casting mills that may have very little rolling/forging reduction, which can have a negative effect on the mechanical properties.
Whats the Difference Between Hot and Cold Rolled Steel? hot rolled material 20crnimo steel bars For other forms, such as bars and plates, materials are sectioned and packaged. Steel shrinks slightly as it cools. Because hot hot rolled material 20crnimo steel bars
HOT ROLLED or COLD FINISHED. Which should you use? The choice depends upon the purpose. Hot rolled bars, without any further finishing, are chosen for many general uses, thus saving you money.
