The SA 516 GR.70N NACE and MR 0103/0175 plates are crafted from carbon steel with a precisely controlled chemical composition that helps resist hydrogen-induced cracking and sulfide stress corrosion. This steel is formulated with optimal levels of carbon, manganese, silicon, and minimal impurities to meet NACE standards. On the mechanical side, the normalized plates boast high yield and tensile strength, impressive notch toughness, and stable performance even at low temperatures. These characteristics ensure excellent weldability, resistance to internal pressure, and reliable service in sour and 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. |
