These plates are crafted to meet international standards and rigorous quality benchmarks, ensuring they deliver outstanding performance in critical applications. With a strong focus on durability, reliability, and customer satisfaction, Phanuphong Steel provides customized solutions to industries around the globe.
The SA 516 GR.65N NACE HIC Plates are mainly made up of carbon, manganese, phosphorus, sulfur, and silicon, along with trace amounts of vanadium and nickel to boost their strength and toughness. These plates are known for their excellent weldability, notch toughness, and consistent microstructure. Typically, they showcase a tensile strength ranging from 415 to 585 MPa and a yield strength of 260 MPa, ensuring they can withstand pressure effectively. With properties tested for impact at low temperatures and a strong resistance to hydrogen-induced cracking, these plates are reliable in sour service environments, making them perfect for critical process industries.
| Grade | ASME SA 516 GR.65N Boiler and Pressure Vessel Steel Plates |
|---|---|
| Width | 1000mm-4500mm |
| Thickness | 5mm-150mm |
| Length | 3000mm-18000mm |
| Supply Condition | As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement. |
| Impact tested | 52° C |
| Tempering | Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F. |
| Applications | Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service. |
