Low-Carbon Steel U-Channels
- Yield Strength: 36,000 psi
- Hardness: Not Rated (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Not Rated
- Specifications Met: ASTM A36
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. This material can be surface hardened with heat treating.
