SPECIFICATION
| 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 deg 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. |
| Process of Manufacturing |
Hot-Rolled (HR) |
