Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts.

This steel is nitrided, which involves the absorption of nitrogen, providing a corrosion-resistant surface that won’t flake or chip. It is comparable to NitroSteel.

Made with more carbon and manganese than other easy-to-machine carbon steels, 1144 carbon steel has a higher yield strength and hardness. Also known as Stressproof, these rods are stress-relieved to minimize warping during machining.

Often called ETD-150, these rods are made from a modified version of 4140 alloy steel and have been drawn at high temperatures for excellent strength.
