Product Overview
Carbon Steel Plate—a flat-rolled metal with varying carbon content—is prized for its strength, versatility, and cost-effectiveness. Available in structural, high-strength, pressure-vessel, and wear-resistant grades, it adapts to a wide range of industrial needs.
Key Grades & Specs
| Grade | Yield (ksi / MPa) | Tensile (ksi / MPa) | Features | Typical Uses |
|---|---|---|---|---|
| A36 | 36 ksi (250 MPa) | 58–80 ksi (400–550 MPa) | Excellent weldability, ductile, easy to machine | Beams, bridges, general construction |
| A572 Grade 50 | 50 ksi (345 MPa) | ~65 ksi (448 MPa) | HSLA, strong yet weldable | Heavy equipment, structural projects |
| A588 | 42–50 ksi | ~70 ksi | Weathering alloy, corrosion-resistant | Outdoor structures, bridges |
| A514 (T-1) | ~100 ksi (700 MPa) | ~110 ksi (760 MPa) | Extremely high-strength, quenched & tempered | Cranes, heavy machinery |
| A516 Grade 70 | 70 ksi (485 MPa) | 70–90 ksi | Pressure vessel-grade with excellent toughness | Boilers, pressure vessels |
| AR400 / AR500 | 155–200 / 200–225 ksi | 200–250 / 225–275 ksi | High-brinell hardness, wear-resistant | Mining, armor, wear plates |
