ASTM A36 hot rolled steel bar has been roll-pressed at very high temperatures—over 1,700˚F, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with.
ASTM A36 steel is the most common of the hot-rolled steels. It is available in a wide variety of shapes. The hot roll process means that the steel was brought to approximate finished size by rolling at elevated temperatures. Its yield strength is significantly less than 1018 – It will bend much more quickly than 1018 will. Machining this material is noticeably more difficult than 1018 steel, but the cost is usually significantly. less.
Hot rolled round bar is a strong, tough, ductile, formable and weldable steel material that can be used for numerous types of applications like cylinder rod and hollow bars. 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.
