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.

Low-Carbon Steel H-Bars
- Yield Strength: 50,000 psi
- Hardness: Not Rated
- Heat Treatable: Yes
- Maximum Hardness After Heat Treatment: Not Rated
- Specifications Met: ASTM A992
Made of stiff low-carbon steel to deflect less under load, these H-bars are commonly used in machine bases, construction, platforms, and frames. Because of its rigidity, low-carbon steel is the most commonly used material for H-bars. These H-bars are less likely to crack from welding than those made of higher-carbon steels, and easier to weld than I-beams because they have a straight flange instead of a radius flange. H-bars are stronger than I-beams, but also heavier.
