Hot rolled carbon steel bar aisi1020/astm1020/s20C is a Hot Roll Chemistry Plate. “10” designates a basic carbon steel and “20” designates the approximate carbon content.
HR 1020 is a general purpose, mild steel with good overall, structural steel properties. 1020 steel demonstrates high machineability capacity & excellent welding characteristics.
Hot rolled carbon steel bar aisi1020/astm1020/s20C is steel that while it is being formed or rolled is heated red-hot. As the steel cools in the open air, the surface oxidizes creating a blue grey scale finish.
Wall thickness tolerances within the coil will not be as uniform or as tight as steel produced as cold rolled. For a listing of standard tubing sizes and gauges that Valmont produces in a hot rolled finish, please visit our Steel Tubing Product Catalog.
