1045 Carbon Steel Round Bar Specifications

While alloy steel round bar comes in a broad range of grades, 1045 is specifically a medium carbon steel option. As a carbon steel, it contains more than 0.08% carbon content and is known for its corrosion resistance and overall strength. A tough alloy like 1045 works well for manufacturing gears, shafts, and other high-wear components.

Lower carbon steel grades are typically more ductile and offer weldability properties. High carbon steel, on the other hand, can be too hard to efficiently machine. Choose 1045 carbon steel for a happy medium of strength and machinability. Ask for more information on the specific mechanical properties and chemistry to see if this round bar grade meets your needs.
