AISI 1045 Carbon steel flat steel hot rolled customized logo
Flat bar is usually a carbon steel alloy which has had the surface condition improved by drawing, peeling or grinding over the hot rolled finish supplied by the steel mill. Advantages achieved include improved machining, less wastage at component production stage, enhancement of physical and mechanical properties and improved dimensional tolerances and straightness.
Flat steel refers to the steel 12-300mm wide, 3-60mm thick, rectangular in section with a slightly blunt edge.Flat steel can be finished steel, can also be used as blank for welded pipe and thin slab for laminated sheet.Main use: flat steel as a forming material can be used for making hoop iron, tools and mechanical parts, used as structural parts of building frame, escalator.

Cold drawn 1045 steel bar is a medium carbon steel grade with higher mechanical properties, fair weldability and limited formability. This grade is widely available and commonly stocked because of its excellent properties and cost. Eaton Steel Bar Company stocks several diameters of this grade to meet your demands quickly. All cold finished material is manufactured to meet ASTM A108 requirements. We also stock many sizes that are JDM QL-2 certified. Grade 1045 cold drawn steel bar provides greater dimensional control, improved straightness, and better surface condition to aid in machining. We commonly supply 1045 cold drawn steel bar to various industries like automotive, agriculture, ATV, and motorcycle.
Hot rolled 1045 steel bar is a medium carbon common steel grade with moderate weldability, higher strength, and impact properties for a variety of applications. 1045 steel is a common grade because of its cost and excellent properties. However, due to its lack of alloying content, this grade has limits on mechanical properties and options for heat treatments.
