ASTM A514 GR A Quenched and Tempered Steel Plate

If you're looking for a high-strength steel plate that delivers exceptional performance in demanding environments, ASTM A514 GR A quenched and tempered steel plate is an excellent choice. This material is designed for structural applications where superior strength and toughness are essential.

At Gangsteel, we specialize in producing and exporting premium ASTM A514 GR A steel plates, ensuring they meet rigorous international standards for quality and reliability.

Quenched and tempered steel like A514 GR A undergoes a specialized heat treatment process: it's heated to high temperatures, rapidly cooled (quenched), and then reheated at a lower temperature (tempered). This enhances its hardness, strength, and resistance to wear while maintaining good weldability and formability. Whether for heavy machinery or construction, this steel plate stands up to tough conditions.

What is ASTM A514 GR A Steel Plate?

ASTM A514 GR A is a high-yield-strength alloy steel plate that's quenched and tempered for enhanced properties. It's part of the ASTM A514 family, which includes various grades suited for welded structures requiring high strength-to-weight ratios.

This grade is particularly valued for its ability to handle heavy loads and impacts without compromising integrity. It's commonly used in thicknesses ranging from 3/16 inch to 6 inches, making it versatile for different project scales. At Gangsteel, we ensure our A514 GR A plates are produced with precision to provide consistent performance in real-world applications.

ASTM A514 GR A Specification

The ASTM A514 specification covers high-strength, quenched and tempered alloy steel plates intended for use in welded bridges and other structures. For Grade A, the plates are available in thicknesses up to 6 inches, with a minimum yield strength that varies by thickness.

Key specifications include compliance with ASTM A514/A514M standards, which outline requirements for chemical composition, mechanical properties, and heat treatment. Plates must be delivered in a quenched and tempered condition to achieve optimal toughness and strength. Gangsteel adheres strictly to these specs, offering plates that are ultrasonic tested and certified for quality.

Chemical Composition

The chemical makeup of ASTM A514 GR A steel plate is carefully controlled to ensure its high-strength characteristics. It includes alloying elements like chromium and molybdenum, which contribute to its durability and resistance to corrosion.

Here's a breakdown of the typical chemical composition (maximum percentages unless specified as a range):

These elements work together to provide excellent weldability and formability, making A514 GR A suitable for fabrication processes.

Mechanical Properties

ASTM A514 GR A boasts impressive mechanical properties that make it ideal for high-stress applications. Its high yield and tensile strength allow for lighter designs without sacrificing safety.

The properties vary slightly by plate thickness:

These values ensure the steel can endure impacts, abrasion, and fatigue, which is why it's favored in industries requiring robust materials.

Applications of A514 Grade A Steel Plate

ASTM A514 GR A steel plate is widely used in sectors where strength and durability are paramount. It's perfect for construction equipment, such as crane booms and excavator arms, where it supports heavy loads and resists wear.

In mining and quarrying, it forms parts of dump trucks and loaders that handle abrasive materials. Agricultural machinery, heavy vehicle frames, and transport trailers also benefit from its toughness. Additionally, it's applied in bridges and structural frameworks, providing reliable support in high-impact environments. Gangsteel has supplied A514 GR A for global projects, proving its versatility and performance.

Equivalent Grades (A514 vs EN 10025-6 S690QL vs JIS G3106 SM570)

ASTM A514 GR A has equivalents in other international standards, offering similar high-strength properties for quenched and tempered steels. These equivalents allow for flexibility in sourcing materials across regions.

For instance, EN 10025-6 S690QL is a European standard with comparable yield strength and toughness, often used in structural engineering. JIS G3106 SM570 from Japan provides similar weldability and is common in construction.

Other detailed standards include GB/T 16270 Q690D (China) and AS/NZS 3678 Grade 450 (Australia/New Zealand), which match in terms of mechanical performance.

Here's a comparison table:

These equivalents ensure compatibility in global projects, though exact matches depend on specific requirements.

Delivery Status

ASTM A514 GR A steel plates are typically delivered in a quenched and tempered (Q&T) condition. This heat-treated state provides the optimal balance of strength, toughness, and ductility right out of production.

At Gangsteel, we ensure plates are shipped with protective packaging to prevent damage during transit. Delivery options include normalized or as-rolled states upon request, but Q&T is standard for maximum performance. We also provide mill test certificates confirming the delivery status meets ASTM specifications.
