ASTM A514 alloy steel plate is known for its high yield strength, weldability, and toughness, even at low temperatures.This grade steel has a min-yield strength of 100 ksi/690 MPa. It’s most commonly used as a structural steel in building construction, for cranes, or other large machines supporting high loads.ASTM A514 should be welded according to procedures suitable for this grade of steel.
A514 is used where a weldable, machinable, very high strength steel is required to save weight or meet ultimate strength requirements.It is also widely used for a wide range of frame and structural components as well as high wear machine components that require high strength, impact and abrasion resistance.
