Cold Roll Round Bar 1144, also called "Stress Relieved" or "Stressproof®", has excellent strength, hardness, and it is easily machined. 1144 is also designed to resist warping during heat treatment. It is typically used in nuts, bolts, arbors, gears, pinions, piston rods, sleeves, shafts, and screws.
Stressproof is a trademark of LaSalle Steel Co.

This 2.5" diameter 1144 carbon steel round bar is cold finished and stress relieved, offering superior strength and machinability compared to standard steel. It also provides better dimensional stability and reduced risk of warping during machining.

Yes, the bar can be custom cut to your specified length before shipping, allowing you to order only the size you need for your project.

1144 carbon steel round bars are commonly used for making shafts, gears, and machine parts where high strength, excellent machinability, and dimensional stability are important.

While 1144 carbon steel offers excellent mechanical properties, it does not have significant corrosion resistance and is best used in dry or controlled environments, or finished with a protective coating if necessary.

The bar is stocked at select warehouses and available for prompt shipping; you can check live availability and select a warehouse closest to you during the ordering process for the fastest delivery.
