Low-Carbon Steel Rods and Discs
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See table
- Fabrication: See table
- Specifications Met: See table
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.
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.
