A514 is a high-strength, quenched and tempered alloy steel plate containing chromium, nickel, and molybdenum as alloying elements. It offers excellent strength, toughness, wear resistance, and weldability, making it suitable for structural components, heavy machinery, and equipment subjected to high impact loads. With a minimum yield strength of 100 ksi and good corrosion resistance, A514 steel plate is commonly used in applications like bridges, pressure vessels, cranes, and heavy construction equipment where high strength and resistance to brittle fracture are critical requirements.
