ASTM A514 Alloy Steel

• High-strength quenched and tempered alloy steel plate produced to ASTM A514 requirements. Engineered for structural applications that require exceptional yield strength, good toughness and reliable weldability.

• Key mechanical characteristics:

  • Quenched and tempered condition for high yield strength.
  • For plates up to 2-1/2" (63.5 mm) thickness: minimum yield strength ≥ 100 ksi (690 MPa).
  • For plates > 2-1/2" and ≤ 6" (63.5–152.4 mm): minimum yield strength typically 90 ksi (620 MPa).
  • Low carbon content and fine-grain practice to support welding and structural performance.

• Typical properties and processing notes:

  • Optimized chemistry and heat treatment deliver a high strength-to-weight ratio, allowing thinner sections and lower assembly weight in many applications.
  • Suitable for welded structures when appropriate welding procedures and qualifications are followed; preheat/post-weld requirements depend on thickness and fabrication details.
  • Supplied as plates in a range of thicknesses (see inquiry for available sizes and finishes).

• Common applications:

  • Heavy equipment frames and chassis
  • Crane booms and lifting equipment
  • Transport trailers and flatbeds
  • Mobile man-lifts and agricultural machinery
  • Welded bridge structures and other high-stress structural components

• Commercial and technical support:

  • Material certificates and mill test reports are typically available on request (chemical analysis, mechanical tests and heat treatment records).
  • Specify required thickness, length, edge condition and any NDT or certification needs when requesting a quote.
