Latham Steel, a reliable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality SA 516 GR.60/70N NACE plates that are perfect for sour-service and high-pressure settings. These normalized carbon steel plates are specifically designed to withstand sulfide stress cracking, adhering to NACE MR0175/ISO 15156 standards, which guarantees dependable performance in environments rich in hydrogen sulfide. With their enhanced toughness, excellent weldability, and consistent mechanical properties, these plates are a great fit for critical pressure-retaining applications. Latham Steel ensures precise thickness, a uniform surface finish, and full compliance with international standards, making SA 516 GR.60/70N NACE plates a trustworthy option for refineries, petrochemical plants, and gas-processing units.
SA 516 GR.60/70N NACE plates are crafted with carefully controlled levels of carbon, manganese, silicon, phosphorus, and sulfur, along with micro-alloying elements that boost toughness and minimize the risk of cracking. Grade 60 offers moderate tensile and yield strength, while Grade 70 delivers superior mechanical performance. The normalization process refines the grain structure, improving ductility, impact resistance, and overall structural reliability. These plates undergo rigorous NACE-compliant testing to ensure they resist sulfide stress cracking (SSC). With stable hardness, strong weldability, and good resistance to brittle fracture, they are well-suited for high-pressure and sour-service applications.
| Grade | ASME SA 516 GR.60/70N Boiler 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. |
