Latham Steel, a reputable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality SA 516 GR.65N NACE HIC Plates designed for sour-service environments where hydrogen-induced cracking (HIC) poses a significant risk. These normalized pressure-vessel plates adhere to strict ASME and NACE standards, making them perfect for equipment that deals with hydrogen sulfide (H₂S) and other corrosive media. With a commitment to exceptional toughness, excellent weldability, and consistent material reliability, Latham Steel employs rigorous quality control and certified testing. Commonly found in refineries, petrochemical plants, and gas processing facilities, SA 516 GR.65N NACE HIC Plates deliver reliable performance in high-pressure, safety-critical industrial settings.
SA 516 GR.65N NACE HIC Plates are crafted from fine-grained carbon steel, featuring controlled amounts of carbon, manganese, silicon, and trace alloying elements to boost strength and crack resistance. These plates undergo a normalization process to enhance toughness, uniformity, and resistance to brittle fractures. They showcase impressive tensile and yield strength, outstanding notch toughness, and robust resistance to hydrogen-induced cracking and sulfide stress cracking. Their mechanical properties remain stable even under fluctuating temperatures and high-pressure conditions. With good weldability and ductility, these plates can be safely fabricated for sour-service pressure equipment.
| 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. |
