ASME SA 516 GR.60/70N NACE PLATES Features

• » Dual Grade Certification: Meets the stringent mechanical and chemical requirements of both Grade 60 and Grade 70, providing maximum flexibility for diverse engineering design specifications.
• » Optimized Normalized Structure: Heat-treated via normalization to ensure a uniform fine-grain microstructure, which results in superior impact strength and consistent performance across the plate.
• » Total NACE Compliance: Fully compliant with NACE MR0175 / ISO 15156 and NACE MR0103, making these plates safe for use in sour gas and oil environments where Sulfide Stress Cracking (SSC) is a risk.
• » High-Pressure Capability: The Grade 70 tensile strength (485-620 MPa) allows for the construction of high-pressure vessels with optimized wall thickness to reduce overall project weight.
• » Excellent Low-Temperature Toughness: Maintains structural integrity and high notch toughness at sub-zero temperatures, typically Charpy V-Notch tested at -46°C for cold climate service.
• » Killed and Fine-Grain Practice: Produced as fully killed steel with controlled aluminum or silicon-aluminum additions to ensure a clean internal structure and excellent weldability.
• » Enhanced Internal Soundness: Undergoes vacuum degassing to minimize hydrogen content and non-metallic inclusions, reducing the risk of internal defects and lamellar tearing.
• » Versatile Fabrication Properties: Exceptional forming and welding characteristics allow for the easy manufacture of complex vessel heads, shells, and nozzle reinforcements.
