Product introduction
A514 Grade Q is for high yield strength, quenched and tempered alloy steel plate of structural quality in thickness of 150mm and under intended primarily for use in welded bridges and other structures.
ASTM 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 Grade 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. Grade Q may be ordered with supplemental Charpy V-notch toughness test requirements.
Applications
Typical applications for A514 Grade Q include transport trailers, construction equipment, crane booms, mobile aerial work platforms, agriculture equipment, heavy vehicle frames and chassis.Chemical composition & Mechanical property
