SA 516 GR.60/70N NACE Plates are made from a blend of carbon, manganese, silicon, and carefully controlled amounts of sulfur and phosphorus to meet rigorous NACE standards. The normalization process refines the grain structure, boosts impact toughness, and ensures stable mechanical properties. These plates deliver impressive tensile strength, dependable yield strength, and robust notch toughness. They excel in resisting hydrogen-induced cracking and sulfide stress corrosion, making them perfect for sour service environments. Their reliable mechanical performance guarantees durability, structural integrity, and stability even under high pressure and fluctuating temperatures.
| 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. |
