Latham Steel is a trusted manufacturer and supplier based in Hamilton, New Zealand, specializing in high-quality SA 516 GR.65N NACE and MR 0103/0175 Plates designed for sour-service and high-pressure settings. These normalized pressure-vessel plates adhere to rigorous ASME and NACE standards, providing outstanding resistance to hydrogen sulfide (H₂S), hydrogen-induced cracking (HIC), and sulfide stress cracking (SSC). With a commitment to material quality, exceptional toughness, and excellent weldability, Latham Steel’s plates are perfect for refineries, petrochemical plants, offshore platforms, and gas processing units. Thanks to thorough inspections and a reliable supply chain, Latham Steel offers steel solutions that are trusted in safety-critical industrial applications.
The SA 516 GR.65N NACE and MR 0103/0175 Plates are crafted from fine-grained carbon steel, featuring controlled amounts of carbon, manganese, silicon, and trace alloying elements. A normalizing treatment boosts toughness, uniformity, and structural stability. These plates deliver high tensile and yield strength, exceptional notch toughness, and impressive resistance to HIC and SSC in sour-gas environments. Their mechanical performance remains consistent under high pressure and fluctuating temperatures, making them ideal for critical pressure-vessel applications. The steel also boasts good weldability and ductility, ensuring safe and reliable fabrication in demanding conditions.
| 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. |
