High-Strength ASTM A514 Grade F Weldable Plate Properties

 

ASTM A514 Grade F is a high-yield-strength, quenched and tempered alloy steel plate under the ASTM A514/A514M standard, known for its excellent toughness, weldability, and resistance to impact and abrasion.

It is designed for structural applications requiring superior strength and durability, even at low temperatures. With a minimum yield strength of 100 ksi (690 MPa) for most thicknesses, Grade F offers a balance of high performance and fabricability, making it suitable for welding with proper precautions.

As a leading manufacturer and exporter, Gangsteel produces premium astm a514 grade f plates, along with other grades like astm a514 grade e and astm a514 grade q, ensuring compliance with international standards.

 

What is ASTM A514 Grade F Weldable Plate

Grade F is part of the A514 family, alloyed for enhanced toughness and abrasion resistance, and is available in thicknesses up to 2-1/2 inches with full strength properties. Its quenched and tempered condition provides superior mechanical properties compared to non-heat-treated steels, allowing for weight reduction in designs. The plate's weldability is a key feature, though it requires controlled heat input to maintain properties.

Gangsteel's ASTM A514/A514M steel plate includes Grade F for demanding applications, with options for thicker plates where yield strength adjusts to 90 ksi.

 

Chemical Composition of ASTM A514 Grade F

The chemical makeup of Grade F includes elements like nickel and copper for improved toughness and corrosion resistance. Below is the typical composition (in weight %, heat analysis) per ASTM specifications:

These properties provide excellent impact resistance and ductility. Additional traits include a modulus of elasticity of about 190 GPa and good fatigue strength.

 

Heat Treatment and Weldability of ASTM A514 Grade F

Grade F is quenched and tempered, heated to 1650°F (900°C), quenched, and tempered at 1100-1300°F (600-700°C) for optimal properties. Weldability is strong, but requires low-hydrogen electrodes, preheating (to 300-500°F for thicker plates), and controlled interpass temperatures to avoid affecting chemical properties. Gangsteel's process ensures machinability (rating ~0.7) and weldable performance for astm a514 grade f.

 

Applications of ASTM A514 Grade F

Grade F is used in high-stress environments like mining equipment, cranes, bridges, and abrasion-resistant components. Its properties suit bucket parts, wear plates, and structural frames. For similar uses, consider astm a514 grade p or astm a514 grade s. Gangsteel's plates are exported with certifications.
