Low-Carbon Steel Rectangular Tubes
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.

Easy-to-Weld Wear-Resistant 8620 Alloy Steel
- Yield Strength: 55,000 psi
- Hardness: Rockwell B85 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C60
- Specifications Met: ASTM A108
While the low carbon content makes 8620 alloy steel easy-to-weld, it's the nickel, chromium, and molybdenum content that provides wear resistance.
