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.

High-Strength Easy-to-Machine 1144 Carbon Steel Hex Bars
- Yield Strength: 100,000 psi
- Hardness: Rockwell C25 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Not Rated
- Fabrication: Cold Drawn
- Specifications Met: ASTM A108, ASTM A311
With more carbon and manganese than other easy-to-machine carbon steel, 1144 carbon steel has higher yield strength and hardness. Also known as Stressproof, these hex bars are stress-relieved to minimize warping during machining. Use them to make parts that require high strength, such as high-strength fasteners and fittings. All meet ASTM standards for quality and performance.
