ASTM A514 GR S | A514 GRADE S STEEL PLATE
ASTM A514 Grade S
High-Yield-Strength, Quenched and Tempered AlloySteel Plate
General Product Description
ASTM A514 Grade S is a quenched and tempered alloy steel plate for structural applications
requiring high yield strength combined with good formability and toughness. A514 Grade S has
a minimum yield strength of 690 MPa [100 ksi] and may be ordered with supplemental Charpy
V-notch impact test requirements.
Applications: Typical applications for A514 Grade S include transport trailers, construction
equipment, crane booms, mobile man-lifts, agricultural equipment, heavy vehicle frames and
chassis, and welded bridge structural members.
Dimensions Available:
Thickness: 4.8 mm – 31.8 mm (0.1875” – 1.25”)
Width: 1,829mm – 2,591 mm (72” - 102”)
Length: 6.10m – 15.2 m (240” - 600”)
Standard plate thicknesses available (96” wide x 240” pattern size) include
4.8, 6.4, 9.5, 12.7, 19.0, 25.4 and 31.8 mm (3/16”, ¼”, 3/8”, ½”, ¾”, 1” and 1-1/4”).
Please inquire for other sizes.
Mechanical Properties
Tensile Test is performed in the transverse direction according to ASTM A6 requirements. The
minimum values are tabulated below:

* For plates up to 0.375”, a Brinell hardness test may be used instead of a tensile test for those plates not
tensile tested in a 15-ton lot.
Charpy V-Notch Impact Toughness requirements may be ordered as a supplementary
requirement. A minimum Charpy V-notch impact energy value of 20 ft-lbs [27 J] at -50°F [-45°C]
in longitudinal specimens is a typical supplemental impact toughness requirement. Please
inquire for applications requiring a specified minimum impact toughness.
