- Sulfur (S): ≤ 0.035%
- Niobium (Nb): 0.005% - 0.05%
- Vanadium (V): 0.01% - 0.12%
- Titanium (Ti): 0.006% - 0.05%
- Chromium (Cr): ≤ 0.30%
- Nickel (Ni): ≤ 0.50%
- Copper (Cu): ≤ 0.40%
- Molybdenum (Mo): ≤ 0.10%
- Nitrogen (N): ≤ 0.015%
- Aluminum (Als): ≥ 0.01%
These precise proportions of elements contribute to the plate's exceptional strength, toughness, and resistance to corrosion and fatigue.
Mechanical Properties:
The A514GrP/A514 Grade P plate demonstrates remarkable mechanical properties after undergoing the quenching and tempering process. Key properties include:
- Yield Strength: ≥ 690 MPa
- Tensile Strength: 760-896 MPa
- Elongation: ≥ 16%
- Impact Temperature: 34-40°C (based on specific requirements)
These properties ensure that the plate can withstand extreme loads and maintain structural integrity in the most challenging environments.
Heat Treatment State:
The A514GrP/A514 Grade P plate is subjected to a meticulous quenching and tempering heat treatment process. This involves heating the plate to a temperature not lower than 900°C, followed by quenching in water or oil. The plate is then tempered at a temperature not lower than 620°C to achieve the desired mechanical properties and microstructure. This process ensures that the plate is optimized for high strength, toughness, and resistance to stress cracking.
Available Sizes and Dimensions:
TJC Steel Group offers A514GrP/A514 Grade P plates in a wide range of sizes and thicknesses to meet various application requirements. Typical dimensions include:
- Thickness: 8 mm to 150 mm (custom thicknesses available upon request)
- Width: 1500 mm to 3800 mm
- Length: 3000 mm to 12000 mm (or as per customer specifications)
Low-Temperature Impact Testing:
The A514GrP/A514 Grade P plate undergoes rigorous low-temperature impact testing to ensure its performance in cold environments. The plate consistently demonstrates high impact energy values, ensuring its reliability in applications where low temperatures are a concern.
Primary Applications:
The exceptional properties of A514GrP/A514 Grade P make it an ideal choice for numerous applications, including:
