Easy-to-Weld A572 Alloy Steel Sheets and Bars

- Yield Strength: 50,000 psi
- Hardness: Rockwell B75 (Medium)
- Maximum Hardness After Heat Treatment: Not Rated
- Specifications Met: ASTM A572
Combining strength with weldability and formability, A572 alloy steel is an economical choice for structural components, such as channels, beams, and framing. It has a low carbon content, making it easy to weld with a variety of welding methods. Stronger than other low-carbon steels, such as A36 steel, it handles heavy loads without fracturing. Tested using ASTM A572, these sheets and bars are safe for jobs that require a yield strength of 50,000 psi or less.
