ASTM A514
The ASTM A514 specification is the Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding used in applications where Yield Strengths of ≥ 100 ksi are required for plates up to 2-1/2" thick, inclusive. Plates > 2-1/2" and ≤ 6" in thickness have a minimum Yield Strength requirement of 90 ksi. Each grade has different chemistry requirements. Typical applications include transport trailers, construction equipment, crane booms, mobile man-lifts, agricultural equipment, heavy vehicle frames and chassis, and welded bridge structural members.
