A514 Heavy Steel Plate

ASTM A514 heavy plate 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 heavy loads.

A514 is used where a weldable, machinable, very high strength steel is required to save weight or meet ultimate strength requirements
