Low-Carbon Steel Hex Bars
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Fabrication: Cold Worked
- Specifications Met: ASTM A108
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's often fabricated into low-strength fasteners and fixture clamps. For added wear resistance, it can be surface hardened with heat treating. These hex bars have been manufactured to meet ASTM A108 standards for quality and performance.
