Quenched and Tempered ASTM A514 for High-Wear Applications

Quenched and Tempered ASTM A514 for High-Wear Applications

Quenched and tempered ASTM A514 steel plates are high-yield-strength alloy steels engineered for superior performance in high-wear environments, offering exceptional toughness, abrasion resistance, and weldability. Under the ASTM A514/A514M standard, these plates are heat-treated to achieve high hardness and strength, making them ideal for applications where durability under abrasive conditions is critical. As a leading manufacturer and exporter, Gangsteel produces premium ASTM A514/A514M steel plate in quenched and tempered forms, including grades like astm a514 grade q and astm a514 grade f, designed for global high-wear demands.

What is Quenched and Tempered ASTM A514 Steel Plates?

ASTM A514 plates are low-carbon quenched and tempered alloys that provide a cost-effective solution for structural and high-wear uses, with yield strengths up to 100 ksi (690 MPa). The quenching and tempering process refines the grain structure, enhancing wear resistance and longevity in abrasive settings. Grades vary to suit specific needs, such as astm a514 grade e for impact-abrasion resistance and astm a514 grade b for general high-wear machinery.

 Gangsteel's ASTM A514/A514M steel plate is available in thicknesses up to 8" for select grades, ensuring versatility for high-wear projects.

The table below outlines common quenched and tempered A514 grades and their high-wear suitability:

Gangsteel's compositions align with ASTM for optimal quenching and tempering.

Mechanical Properties of Quenched and Tempered ASTM A514

Post-heat treatment, A514 plates exhibit high wear resistance with consistent properties. The table below summarizes typical values:

These enable long-lasting performance in abrasive conditions.

Quenching and Tempering Process for ASTM A514

The heat treatment involves austenitizing at 1550-1650°F (843-899°C), quenching in water or oil, and tempering at 1100-1300°F (593-704°C) to balance hardness and toughness. This process refines the grain for superior wear resistance. Gangsteel's facilities ensure precise treatment for grades like astm a514 grade h, avoiding over-tempering that could reduce wear properties.

High-Wear Applications of Quenched and Tempered ASTM A514

A514 is suited for high-wear scenarios like mining equipment, aggregate removal, dump bodies, and construction machinery. Examples include bucket components, scraper blades, and wear plates in quarries. For offshore or abrasive uses, consider astm a514 grade p. Gangsteel's plates deliver extended service life in these applications.
