ASTM A514 high strength steel plate

ASTM A514 Alloy Steel Plate

The A514 plate steels are a group of quenched and tempered alloys with many attractive advantages and characteristics. It has a minimum tensile strength of 100 ksi (689 MPa) and at least 110 ksi (758 MPa) ultimate. Plates from 2.5 inches to 6.0 inches have a specified tensile strength of 90 ksi (621 MPa) and 100 - 130 ksi (689 - 896 MPa) ultimate. A514 plate also provides good weldability, and toughness at low atmospheric temperatures. The ASTM A514 group is designed for a wide range of structural uses as well as machinery and equipment.  However, the primary use  is as a structural steel in building construction. This group of steel, which also includes A517, alloy steel combine optimum strength, toughness, corrosion resistance, impact-abrasion resistance, and long-term economy.

A514 steel plate
ASTM A514 is most commonly used as structural steel in cranes and large heavy-load machines. Gnee steel stocks ample inventory of A514.
Overview:
Commonly used as structural steel in cranes or large heavy-load machines, A514 offers high strength with weldable, machinable properties.
Also referred to as T-1 steel.
Quenched and tempered for increased strength.
Available in eight grades: B, S, H, Q, E, F, A and P.
Available in heavy plate thicknesses (3-inches or greater).
Suitable in lower temperatures. Charpy impact test results for specific climates available.
