ASTM A572 Grade 50 steel is widely used in:
ASTM A572 Grade 50 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 – 4.00 / 4.78 – 102 | 72 – 131.9 / 1800 – 3350 | 240 – 1020 / 6100 – 25910 |
| Temper Leveled Plate | 0.100 – 0.625 / 2.54 – 15.9 | 48 – 96 / 1200 – 2400 | 72 – 720 / 1800 – 18300 |
ASTM A572 Grade 50 has good weldability due to its low carbon content. It can be welded using common methods such as shielded metal arc welding (SMAW) and gas metal arc welding (GMAW). The machinability is rated at 66% of B1112, with an average cutting speed of 110 ft/min.
