ASTM steel brushed bar/bright annealing polishing round bar

Polished steel round bar is a medium carbon steel bar with good strength and impact properties. It is commonly used in applications requiring high strength and toughness, such as gears, axles, shafts, and hydraulic cylinders. The steel round bar is often heat treated to improve its mechanical properties, such as hardness and tensile strength. It is also commonly used in the manufacturing of machinery parts and components. 1045 steel round bar is available in various sizes and can be cut to the desired length.
