Product Introduction

ASTM A514, also known as T‑1 steel plate, is a quenched and tempered, high‑yield alloy steel designed for heavy-load, structural, and wear-intensive applications. With exceptional strength, weldability, and machinability, A514 stands out for rugged performance in cranes, mining gear, bridges, and more .


 Key Product Specifications

  • Grades Available: B, S, H, Q, E, F, A, P

  • Thickness:

    • B/F/H/S: 3/16″–2½″

    • E: up to 6″; Q: up to 8″ 

  • Width: 48″–120″ (1,200–3,000 mm)

  • Length: Up to 480″ (12,200 mm)


Chemical & Mechanical Essentials

  • Chemical Composition (Grade B, typical):
    C 0.12–0.21%, Mn 0.70–1.00%, Cr 0.4–0.65%, Mo 0.15–0.25%, V 0.03–0.08%, trace B, Si 

  • Mechanical Properties:

    • Yield Strength: ≥100 ksi (690 MPa)

    • Tensile: 110–130 ksi (760–900 MPa)

    • Elongation: ≥16–18% 

    • Brinell Hardness: 235–293 HB (approx. 26 HRC)


Our Advantages

  1. Superior Strength-to-Weight Ratio – Delivers roughly twice the yield strength of A572 50, ideal for lighter yet stronger structures

  2. Excellent Weldability – Compatible with standard procedures and preheat recommendations for 2½″+ plates

  3. Good Machinability – CNC and carbide tooling accommodate typical CPU requirements

  4. Hardness & Toughness – Quenched and tempered structure resists abrasion and impact

  5. Broad Grade & Size Options – Eight grades in cuts up to 8″ thick, 10′ wide, and 40′ long


Core Applications

  • Cranes & Heavy Equipment – Booms, frames, truck beds

  • Mining & Material Handling – Bucket liners, chutes, scraper blades

  • Bridge & Structural Fabrication – High-strength girders, gussets

  • Industrial Manufacturing – Tooling plates, work-holding fixtures requiring impact resistance

  • Military & Defense – Blast shields, structural components, armored sections


 Grades & Common Use cases

  • Grade B: Standard high-strength option up to 1¼″ thick

  • Grade E/Q: Thick-plate grades (up to 6″ and 8″) with enhanced alloy content for deep hardening 

  • Grade S/H/F: Designed for intermediate thicknesses with balanced weldability and toughness
