SA 516 GR.60/70N NACE Plates are carbon steel plates specifically designed to enhance notch toughness and resist hydrogen-induced cracking in sour environments. Their chemical makeup primarily consists of controlled amounts of carbon, manganese, and silicon, while keeping sulfur and phosphorus levels low to comply with NACE standards. The normalized heat treatment process improves the grain structure and toughness of the plates. In terms of mechanical properties, GR.60 has lower tensile and yield strength compared to GR.70, which offers higher strength levels. Both grades are known for their excellent impact resistance, good ductility, and dependable performance under pressure and low 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. |
