Esha Steel, a reputable manufacturer and supplier located in Kolkata, specializes in high-quality SA 516 GR.65N NACE and MR 0103-0175 Plates, crafted to meet the rigorous demands of sour service and high-pressure industrial applications. These plates adhere to NACE MR0175 and MR0103 standards, providing outstanding resistance to sulfide stress corrosion, hydrogen-induced cracking, and wet H₂S environments. Thanks to the normalized rolling process, these plates boast improved toughness, structural stability, and reliable performance even at elevated temperatures. Esha Steel maintains strict quality control and precision manufacturing, making these plates perfect for refineries, gas-processing plants, petrochemical units, and pressure vessel fabrications that prioritize safety and durability.
SA 516 GR.65N NACE and MR 0103-0175 Plates are mainly made up of carbon, manganese, silicon, along with carefully controlled amounts of sulfur and phosphorus to meet strict sour service standards. The normalizing treatment enhances the grain structure, boosting toughness, ductility, and impact strength. These plates deliver a balanced combination of tensile and yield strength, exceptional notch toughness, and robust resistance to sulfide stress corrosion and hydrogen-induced cracking. Built to withstand high pressure and temperature variations, they guarantee reliable mechanical performance and long-lasting structural integrity in demanding industrial settings.
| Grade | ASME SA 516 GR.65N 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. |
