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.
| Grade | Product type | Thickness (in) |
Width (in) |
Length (in) |
|---|---|---|---|---|
| Grade E | Plate | 0.185 - 6.00 | 60 - 131.9 | 73 - 590 |
Tensile Properties: Tensile testing is performed in the transverse direction according to ASTM A6 requirements. The tensile property and hardness requirements are tabulated below:
| Grade | Product type | Thickness (in) |
Yield strength (min ksi) |
Tensile strength (ksi) |
Elongation in 2" (min %) |
Reduction of area 1) (min %) |
Reduction of area 2) (min %) |
Hardness 3) (HBW) |
|---|---|---|---|---|---|---|---|---|
| Grade E | Plate | 0.185 - 0.750 | 100 | 110 - 130 | 16 | 35 | — | 235 - 293 |
| Grade E | Plate | 0.751 - 2.50 | 100 | 110 - 130 | 16 | 35 | 45 | — |
| Grade E | Plate | 2.51 - 6.00 | 90 | 100 - 130 | 14 | — | 45 | — |
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.
