Esha Steel, a prominent manufacturer and supplier located in Kolkata, specializes in high-performance SA 516 GR.70N NACE and MR 0103-0175 Plates, crafted for exceptional reliability in tough industrial settings. These plates are engineered to comply with the rigorous NACE MR0175 and MR0103 standards, providing remarkable resistance to sulfide stress cracking, hydrogen-induced cracking, and corrosion in sour service conditions. With a normalized rolling process that boosts toughness and durability, Esha Steel ensures these plates uphold excellent structural integrity even under high pressure and temperature. Commonly found in petrochemical plants, refineries, and gas-processing units, these plates guarantee safety, longevity, and consistent performance in critical applications.
SA 516 GR.70N NACE and MR 0103-0175 Plates are made from a blend of carbon, manganese, silicon, and carefully controlled amounts of phosphorus, sulfur, and micro-alloying elements to meet stringent NACE standards. The normalization process enhances grain refinement, ductility, and impact toughness. These plates boast high tensile and yield strength, outstanding notch toughness, and exceptional resistance to hydrogen-induced cracking and sulfide stress corrosion. Specifically designed for sour service environments, they maintain stability under high temperatures and pressures, ensuring reliable mechanical performance, corrosion resistance, and long-term structural safety for demanding industrial 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. |
