ASTM A514 GR E Quenched and Tempered Steel Plate supplier

ASTM A514 GR E Quenched and Tempered Steel Plate

If you're looking for a high-strength steel plate that offers superior yield strength combined with excellent low-temperature toughness and weldability, ASTM A514 GR E quenched and tempered steel plate is an outstanding option for rigorous structural demands. This alloy steel performs exceptionally in cold environments and high-impact scenarios, making it ideal for applications in offshore platforms, heavy machinery, and bridges. At Gangsteel, we specialize in manufacturing and exporting high-quality ASTM A514 GR E plates, produced to exacting international standards to ensure dependable quality and performance customized to your specifications.

Our A514 GR E plates are processed through a precise quenching and tempering method: heated to high temperatures, rapidly cooled to achieve hardness, and then tempered to optimize toughness. This creates a material that's robust yet formable, suitable for welding into complex structures while maintaining durability. With our deep industry knowledge, Gangsteel ensures every plate is rigorously tested, enabling your projects to endure extreme conditions reliably.

What is ASTM A514 GR E Steel Plate?

ASTM A514 GR E is a quenched and tempered alloy steel plate engineered for high-yield-strength in welded constructions. As part of the A514 series, Grade E features alloying elements like chromium, molybdenum, and titanium that enhance its impact resistance, particularly at low temperatures.

This grade is well-suited for thicknesses up to 6 inches, retaining strong mechanical properties under load. Gangsteel produces A514 GR E plates that are flexible for fabrication, integrating smoothly into designs for equipment such as crane booms, mining gear, or cold-climate structures.

ASTM A514 GR E Specification

The ASTM A514 standard sets guidelines for high-strength, quenched and tempered alloy steel plates for structural welding. Grade E specifies plates up to 6 inches thick, with yield strength calibrated by thickness to maximize low-temperature performance.

Gangsteel's plates fully conform to ASTM A514/A514M, including essential heat treatment and testing. We provide additional options like enhanced Charpy testing to exceed your project requirements.

Chemical Composition

The chemical composition of ASTM A514 GR E is carefully balanced for enhanced strength and low-temperature resilience, with alloys improving hardenability and resistance to brittleness. We manage this via ladle (melt) analysis during production and product analysis on the finished plate, incorporating minor tolerances per ASTM A6.

This formulation ensures our plates thrive in challenging, cold-stress applications.

Mechanical Properties

ASTM A514 GR E provides exceptional mechanical characteristics for structural durability, with values varying by plate thickness to preserve balance. Critical features include high yield strength (deformation resistance), tensile strength (load capacity), elongation (ductility for shaping without breaking), Brinell hardness (wear resistance), and superior low-temperature impact toughness (Charpy V-notch testing, ensuring reliability down to -60°F with minimum 20 ft-lb supplemental values).

Gangsteel's plates are optimized for environments requiring fatigue resistance and cold-weather performance. Elongation is measured over a 2-inch gauge, hardness supports abrasive conditions, and Charpy metrics confirm toughness in sub-zero settings.

Applications of A514 Grade E Steel Plate

Gangsteel's ASTM A514 GR E steel plate is highly versatile in sectors demanding high strength and low-temperature resilience. It's frequently used in offshore drilling rigs and platforms, where it withstands harsh marine conditions and cold impacts.

In mining and construction, our plates construct durable crane components and heavy loaders that operate in frigid climates. Agricultural equipment, vehicle frames in arctic regions, and structural bridges also utilize its excellent toughness. We've supplied GR E for worldwide projects, demonstrating its effectiveness in extreme environments.

Equivalent Grades for ASTM A514 Grade E

ASTM A514 Grade E corresponds to international quenched and tempered high-strength steels, reflecting its composition (e.g., high Cr-Mo for toughness) and properties (yield ~620-690 MPa, tensile 690-895 MPa, enhanced low-temp impact). Listings are limited to direct equivalents for structural uses. The table below covers major standards per country/region, focusing solely on precise matches.
