Tight-Tolerance Low-Carbon Steel Bars
Sometimes called flat stock, these bars have a thickness and width that are precision ground to a tight tolerance. They’re low-carbon steel, also known as mild steel, which is easy to machine, form, and weld. Use them for fabricating parts that don’t require high strength, such as fixture clamps and mounting plates. For added wear resistance, the surface can be hardened with heat treating. All have been manufactured to meet ASTM A36 standards for quality and performance.

Low-Carbon Steel Sheets and Bars
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as fixture clamps, mounting plates, and spacers. Some of this material can be surface hardened with heat treating.
Ground sheets are decarb-free for a uniform surface that will consistently accept heat treating.
Steel that meets ASTM A109 or A36 complies with standards for materials.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

- 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.
Cold-worked rods and discs have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.
