Easy-to-Weld 4130 Alloy Steel Sheets and Bars

- Yield Strength: 50,000 psi
- Hardness: Rockwell B85 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C49
- Fabrication: See table
- Specifications Met: SAE AMS6350, SAE AMS6351
A low carbon content makes this 4130 alloy steel easy to weld. Also known as chrome-moly steel, it’s often used for pressure vessels and structural supports. It can be surface hardened with heat treating for added wear resistance. These sheets and bars have been manufactured to meet SAE standards for quality and performance.

Zinc-Galvanized Low-Carbon Steel Sheets and Bars

These sheets and bars are zinc galvanized for good corrosion resistance. Also known as mild steel, low-carbon steel is easy to machine and form. It's widely fabricated into parts that don’t require high strength, such as enclosures, brackets, and mounting plates. All have been manufactured to meet ASTM A653, ASTM A123, or ASTM A108 standards for quality and performance.
Zinc-coating weight designation indicates the level of corrosion resistance. A higher number means there’s a thicker coating and greater corrosion protection.

High-Temperature Aluminized Low-Carbon Steel Sheets

- Yield Strength: See table
- Hardness: Not Rated
- Heat Treatable: No
- Fabrication: Cold Worked
- Specifications Met: ASTM A463
Coated with an aluminum-silicon alloy, these sheets resist corrosion while withstanding long-term exposure to high temperatures. Low-carbon steel, also known as mild steel, is easy to machine, form, and weld. Use these sheets in drying ovens, furnaces, and smokestacks. They have been manufactured to meet ASTM A463 standards for quality and performance.

Paintable Galvannealed Low-Carbon Steel Sheets

- Yield Strength: 30,000 psi
- Hardness: Not Rated
- Heat Treatable: No
- Specifications Met: ASTM A653
The galvannealed coating allows these low-carbon steel sheets to be painted without prepping the surface. They're easier to weld and more scratch resistant than zinc-galvanized steel sheets. Low-carbon steel, also known as mild steel, is easy to machine and form. Use these sheets for outdoor signs, cabinets, and doors.
