What is the Composition of A514 Grade F?

ASTM A514 Grade F is a high-yield-strength, quenched and tempered alloy steel plate known for its excellent toughness, abrasion resistance, and weldability, making it suitable for structural applications in heavy machinery and construction. Its chemical composition is carefully controlled to achieve these properties, with alloying elements like nickel and copper enhancing impact resistance and durability.

As a leading manufacturer and exporter, Gangsteel produces premium astm a514 grade f plates, ensuring compliance with ASTM A514/A514M standards through precise alloying and heat treatment.

Chemical Composition of A514 Grade F

The chemical composition of ASTM A514 Grade F is specified in the ASTM A514/A514M standard, with variations allowed based on heat analysis. Below is a detailed table of the typical composition (in weight %):

Note: Values are maximum unless a range is specified. Gangsteel's astm a514 grade f plates are manufactured with tight controls on these elements to ensure optimal performance, similar to related grades like astm a514 grade e but with added nickel for enhanced properties.

Mechanical Properties Influenced by Composition

The composition of A514 Grade F contributes to its mechanical properties, including a minimum yield strength of 100 ksi (690 MPa) for thicknesses up to 2-1/2" and Brinell hardness of 235-293 HBW. This makes it ideal for abrasive environments, with good machinability when proper techniques are used. Gangsteel's production ensures these properties through advanced quenching and tempering.

Heat Treatment and Processing

A514 Grade F requires quenching and tempering to achieve its composition-driven properties, typically heated to 1650°F (900°C), quenched, and tempered at 1100-1300°F (600-700°C). Gangsteel's ASTM A514/A514M steel plate lineup includes Grade F for customized applications.

Applications of A514 Grade F

Due to its composition, ASTM A514 Grade F is used in mining equipment, cranes, and structural components where abrasion resistance is key. Gangsteel's plates support these with reliable quality.
