ASTM A514 Grade P (A514 Gr.P) quenched and tempered alloy steel plate

ASTM A514 Grade P (A514 Gr.P) quenched and tempered alloy steel plate

On the premise of meeting the strength requirements and not increasing the carbon content, the hardenability and temper softening resistance of A514 Gr.Q steel can be improved by adding elements such as Cr, Mo, V, and Cu in an appropriate amount. -- Jan 01, 70

ASTM A514 Grade P (A514 Gr.P) steel is a quenched and tempered alloy steel plate with high yield strength and tensile strength. It performs well in yield strength and tensile strength, as well as notch toughness and corrosion resistance. On the premise of meeting the strength requirements and not increasing the carbon content, the hardenability and temper softening resistance of A514 Gr.Q steel can be improved by adding elements such as Cr, Mo, V, and Cu in an appropriate amount.

Main performance
A514GrP quenched and tempered alloy steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, it has good corrosion performance and certain wear resistance.

Cutting
ASTM A514 tempered and quenched alloy steel plates can be cut with plasma, oxy-Acetylene, laser, and water jet, as well as with abrasive cut off saws.

Machining
Drilling, countersinking, counterboring, tapping, milling, and general machining can be done with conventional equipment and carbide tools.

Welding
A514 Grade P steel has excellent weldability and can be welded with simple procedures. Ideal welding wires include our tensaweld workmate for general purposes and tensaweld nickel-90 for increased tensile strength in the weld joint.

ASTM A514 Grade P application field
A514 Gr.P steel plate is mainly used in places where requiring high tensile strength and high yield, such as drilling rigs, lifting gears, oil derricks, coal mine hydraulic supports, electric shovel, electric wheel dump trucks, loaders, bulldozers used in mines and various engineering constructions, all kinds of cranes, engineering vehicles, large excavators, marine drilling platforms, mining equipment.
