SA 516 GR.70N NACE and MR 0103-0175 Plates are specifically designed carbon steel plates for moderate to lower-temperature applications, particularly in sour service environments. These plates typically consist of carbon (0.27%), manganese (0.85–1.20%), phosphorus (max 0.035%), and sulfur (max 0.035%), along with additional elements to comply with NACE MR0175 and MR0103 standards for resistance to hydrogen-induced cracking. They boast impressive mechanical properties, including a minimum tensile strength of 485–620 MPa and a minimum yield strength of 260 MPa. When normalized, these plates exhibit enhanced ductility and notch toughness, making them perfect for pressure vessels and other critical applications.
| 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. |
