The 1144 carbon steel round bar offers excellent strength and machinability, making it ideal for precision parts. The stress relieving process increases dimensional stability and reduces the risk of warping during machining.

Yes, the bar can be cut to size using standard metal cutting equipment, allowing you to order the length you need for your specific project.

This carbon steel alloy has only moderate corrosion resistance and is not recommended for outdoor or highly corrosive environments without protective treatment.

Common uses include shafting, fasteners, and high-precision machined components where strength and reliable performance are required.

This product is stocked in multiple warehouses for efficient shipping, so it's readily available to meet your project timelines.

Yes, this 0.75 inch diameter round bar can be cut to your required length using standard metal cutting equipment, with multiple length options available up to 144 inches.

The 1144 alloy offers excellent strength and hardness along with high machinability (rated 83), and the stress relieved cold finish process reduces warping during machining, making it ideal for precision components.

No, the 1144 carbon steel has only moderate corrosion resistance and is not recommended for outdoor or highly corrosive environments unless additional protective treatments are applied.

Typical uses include shafts, fasteners such as nuts and bolts, arbors, gears, pinions, piston rods, sleeves, and screws where strength and dimensional stability are important.

Yes, a material test report (MTR) is available for this product to verify its chemical and mechanical properties.
