The 1144 Stress Relieved carbon steel round bar offers high strength, excellent machinability, and good wear resistance. Its stress-relieved condition helps minimize warping during machining, making it ideal for precision parts.

Yes, the 1144 Stress Relieved round bar is known for its superior machinability and is easily cut to custom sizes, making it suitable for applications requiring precise, detailed work.

This round bar is commonly used in shafts, machinery parts, and components requiring high strength and wear resistance, as well as in scenarios where consistent dimensional stability is important.

The 1144 Stress Relieved round bar has only moderate corrosion resistance, so it is not recommended for use in environments where exposure to moisture or corrosive elements is a concern. For greater corrosion resistance, a different alloy may be preferable.

The 1144 round bar is typically stocked in multiple warehouses for quick shipping, and availability can be checked online for local pickup or fast delivery options.

Yes, this 0.5" diameter round bar is easily cut to custom sizes with quick processing available from the warehouse, making it ideal for projects requiring precise length specifications.

The 1144 alloy in a stress-relieved, cold finish condition offers excellent machinability with a rating of 83, allowing for smooth, precise machining with minimal warping.

This round bar is commonly used for manufacturing nuts, bolts, shafts, gears, and other components that require high strength, hardness, and dimensional stability.

The 1144 round bar has moderate corrosion resistance and is not recommended for environments with high moisture or corrosive exposure.
