SA 516 GR.70N NACE and MR 0103-0175 plates are carbon steel plates designed with enhanced resistance to hydrogen-induced cracking (HIC). Typically, they contain carbon (up to 0.27%), manganese (0.85–1.20%), phosphorus (up to 0.035%), sulfur (up to 0.035%), and silicon (0.13–0.45%). These plates boast impressive mechanical properties, including a minimum tensile strength of 485–620 MPa and a yield strength of 260 MPa, along with improved notch toughness thanks to normalizing treatment. Specifically designed for sour service, they comply with NACE MR0175/ISO 15156 and MR0103 standards, making them ideal for pressure vessels operating in harsh, 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. |
