TJC Steel Group proudly presents the A514GrS/A514 Grade S, an exceptional quenched and tempered high-strength alloy steel plate that embodies unparalleled strength, durability, and versatility. This steel grade adheres to the stringent standards set by ASTM, ensuring its suitability for demanding applications across various industries.

Chemical Composition:

The A514GrS alloy steel plate boasts a precise chemical composition tailored for optimal performance. Its elemental makeup includes:

- Carbon (C): ≤ 0.20% - Ensuring high strength while maintaining sufficient ductility

- Silicon (Si): ≤ 0.35% - Enhancing overall toughness and wear resistance

- Manganese (Mn): 1.2% - 1.7% - Improving hardenability and strength

- Phosphorus (P): ≤ 0.025% - Minimizing embrittlement and crack sensitivity

- Sulfur (S): ≤ 0.005% - Further reducing embrittlement risk

Additionally, trace amounts of chromium, nickel, and molybdenum may be added to enhance corrosion resistance and high-temperature performance, respectively.

Mechanical Properties:

The A514GrS plate exhibits remarkable mechanical properties, including:

- High Yield Strength: Capable of withstanding significant loads without permanent deformation

- Tensile Strength: Exceeding expectations for high-stress applications

- Elongation: Maintaining sufficient ductility for forming and welding processes

- Toughness: Ensuring resistance to impact and fracture under extreme conditions

The specific mechanical properties may vary slightly based on the heat treatment and delivery conditions.

Heat Treatment Status:

The A514GrS plate undergoes a rigorous heat treatment process to achieve its desired properties. The quenching step involves heating the steel to a temperature not less than 900°C, followed by rapid cooling in water or oil to harden the material. Subsequently, tempering at a temperature not less than 620°C is performed to relieve internal stresses and improve toughness without compromising strength.

Production Size Range:

TJC Steel Group offers A514GrS plates in a versatile range of dimensions to meet specific project requirements:

- Thickness: Up to 150mm, suitable for heavy-duty applications

- Width: 1500mm - 4200mm, accommodating various fabrication needs

- Length: Up to 12000mm, ensuring seamless integration into large structures

Low-Temperature Impact Testing:

To ensure the plate's reliability in cold environments, low-temperature impact testing is conducted. This assessment verifies the material's ability to withstand sudden loads without fracture, even at subzero temperatures.

Main Application Scenarios:

The A514GrS alloy steel plate finds widespread applications in sectors that demand exceptional strength and durability:

1. Shipbuilding & Offshore Engineering: Used in the construction of ship hulls, ocean platforms, drilling rigs, and supporting structures, enhancing corrosion resistance and withstanding harsh marine environments.
