ASTM A514 Grade E 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 E 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 to 6 inches in thickness. Grade E may be ordered with supplemental Charpy V-notch toughness test requirements.
Applications
Typical applications for A514 Grade E include transport trailers, construction equipment, crane booms, mobile aerial work platforms, agriculture equipment, and heavy vehicle frames and chassis.
Tensile Properties: Tensile testing is performed in the transverse direction according to ASTM A6 requirements. The tensile property and hardness requirements are tabulated below:
1) Reduction in area for 1.5 in. wide rectangular tension specimen.
2) Reduction in area for 0.5 in. round tension specimen.
3) For plates up to 0.375 in., a Brinell hardness test may be used instead of a tensile test for those plates not tensile tested in a 15 ton lot.
