Product Introduction

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

Why Choose Our Carbon Steel Plates?

  2. Certified Quality – ASME PED, EN 10204 3.2 and third-party testing ensure reliability.

  3. Precision Manufacturing – Clean cut-to-size availability, ultrasonic testing optional.

  4. Global Reach, Local Service – 20+ years experience, shipments worldwide, technical support.

  5. Cost-Efficient Lifecycle – Smart material choice with high performance-to-cost ratio.


Applications Across Industries

  • Construction: A36 & A572 for beams, frames, storage bins.

  • Infrastructure: A588 plates in bridges and outdoor structures.

  • Pressure Vessels: A516/SA537 in boiler and tank manufacturing.

  • Heavy Equipment: A514 in cranes, A572 in machinery platforms.

  • Mining & Wear Environments: AR400/500 for chutes, liners, dump beds.


Working with Carbon Steel Plates

  • Cutting: Laser (<¼″), plasma / waterjet (thick plates).

  • Machining: Carbide tools; monitor chatter on high-carbon grades.

  • Welding: MIG/TIG/Stick; preheat for thick/quench-strength plates.

  • Surface Treatment: Galvanizing, painting, or powder-coating for corrosion resistance.
