They provide SA 516 GR.65N plates that meet NACE and MR 0103/0175 standards, ensuring they can handle tough operating conditions. With state-of-the-art normalizing facilities, rigorous quality control measures, and a team of seasoned experts, Marzouk Steel consistently delivers plates that boast reliable performance and uniform mechanical properties. Catering to the oil and gas, petrochemical, refinery, and power sectors, the company prioritizes safety, compliance, and building lasting partnerships with its customers.
The SA 516 GR.65N NACE and MR 0103/0175 plates are crafted from carbon steel with a precisely controlled chemical makeup designed to withstand hydrogen-induced cracking and sulfide stress corrosion. This material features optimized levels of carbon, manganese, silicon, and limited impurities to align with NACE standards. On the mechanical side, these normalized plates provide greater yield and tensile strength compared to Grade 60, along with excellent notch toughness and stable performance in low temperatures. These characteristics ensure they are easy to weld, resistant to pressure, and dependable in sour environments.
| 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. |
