SA 516 GR.70N NACE HIC Plates are crafted from low-carbon pressure vessel steels, featuring controlled amounts of manganese, silicon, and microalloying elements to boost strength and toughness. The low levels of sulfur and phosphorus, combined with calcium treatment, enhance their resistance to hydrogen-induced cracking. A normalized heat treatment process refines the grain structure, ensuring consistent mechanical properties. These plates showcase impressive tensile strength, good yield strength, excellent notch toughness, and outstanding weldability, making them ideal for low-temperature and high-pressure applications in corrosive environments.
| Grade | ASME SA 516 GR.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. |
