Latham Steel, a reputable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality SA 516 GR.60/70N NACE HIC plates designed for tough sour-service and high-pressure applications. These plates are normalized to boost their toughness and stability, and they go through rigorous testing in line with NACE MR0175/ISO 15156 standards to guarantee outstanding resistance to hydrogen-induced cracking (HIC) and sulfide stress cracking. Built for environments with hydrogen sulfide, these plates offer remarkable durability and weldability. Latham Steel is committed to delivering consistent mechanical performance, precise thickness control, and top-notch material integrity, making them perfect for pressure vessels and refinery equipment in corrosive settings.
SA 516 GR.60/70N NACE HIC plates are made with carefully controlled levels of carbon, manganese, silicon, sulfur, and phosphorus, along with micro-alloy additions to enhance toughness and minimize crack sensitivity. Grade 60 offers moderate strength, while Grade 70 provides higher tensile and yield values. The normalizing treatment refines the grain structure, improving ductility and impact resistance. These plates are subjected to HIC and SSC testing to ensure they perform safely in sour environments. With stable hardness, excellent weldability, and strong resistance to brittle fracture, they are dependable materials for pressure-bearing and corrosive industrial applications.
| Grade | ASME SA 516 GR.60/70N 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. |
