ASTM A572 Grade 55 steel is commonly used in:
ASTM A572 Grade 55 is typically produced through controlled rolling processes. Available dimensions include:
| Product Type | Thickness (in/mm) | Width (in/mm) | Length (in/mm) |
|---|---|---|---|
| Mill Plate | 0.188 – 2.00 / 4.78 – 50.8 | 72 – 120 / 1800 – 3050 | 120 – 1020 / 3050 – 25910 |
| Temper Leveled Plate | 0.100 – 0.625 / 2.54 – 15.9 | 48 – 96 / 1200 – 2400 | 72 – 720 / 1800 – 18300 |
ASTM A572 Grade 55 has good weldability due to its controlled chemical composition. It can be welded using common methods such as shielded metal arc welding (SMAW) and gas metal arc welding (GMAW).
| Grade | Yield Strength (min ksi) | Tensile Strength (min ksi) |
