Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles. You can surface harden this material for added wear resistance. All have been manufactured to meet ASTM standards for quality and performance.
Cold-worked rods and discs have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.
Hot-rolled rods and discs are great for forming and fabricating. The steel undergoes less stress in the finishing process and has a little more give, so you can more easily bend and form it. It does however have a rougher surface finish than cold-worked steel.

An oversized diameter allows for finishing to your exact requirements. Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often used for gears, pulleys, rollers, and bushings.
