A514 Grade Q is a quenched and tempered alloy steel plate used in structural applications that require high yield strength combined with good formability and toughness.A514 Gr.Q has a minimum yield strength of 100 ksi up to 2.5 inches in thickness and 90 ksi for plates greater than 2.5 inches up to 6 inches in thickness.
Compared with ordinary steel plates, A514 Gr.Q high strength steel plates have higher tensile strength and impact resistance, and can withstand higher pressure and heavy loads. In addition, it has excellent wear and corrosion resistance, making it perform well in harsh working environments.
