What features do ASTM A514 grades have

ASTM A514 steel plate is a steel plate material known for its high yield strength, weldability, and toughness, even at low temperatures. And ASTM A514 is a low carbon quenched and tempered alloy steel that is a low-cost, high performing material for structural use and high wear machine applications.
A514 steel plate meets the ASTM International standard A514. This steel plate has a yield strength of 100,000 psi (100 ksi or approximately 700 MPa).
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.
