Filiz Steel, based in Istanbul, Turkey, is a reputable manufacturer and supplier of top-notch SA 516 GR. 65N plates that adhere to NACE MR 0103 and MR 0175 standards. These plates are specifically crafted for sour service and highly corrosive environments, making them essential for the oil, gas, and petrochemical sectors. Filiz Steel takes pride in ensuring that each plate undergoes rigorous testing for notch toughness, hydrogen-induced cracking resistance, and sulfide stress corrosion, guaranteeing their reliability in demanding service conditions. With a solid infrastructure and stringent quality assurance practices, Filiz Steel consistently delivers certified products to clients around the globe.
The SA 516 GR. 65N NACE plates are carbon steel plates that have been normalized to enhance their mechanical performance. Typically, their chemical makeup includes Carbon (≤0.26%), Manganese (0.60–1.35%), Phosphorus (≤0.035%), Sulfur (≤0.010% for NACE), and Silicon (0.15–0.40%). These plates boast a minimum yield strength of 240 MPa and a tensile strength that ranges from 450 to 585 MPa. They are specifically engineered to meet the NACE MR 0103 and MR 0175 standards for resistance to sulfide stress cracking, which is crucial in sour environments. The “N” in their designation indicates normalization, a process that improves toughness and grain structure, making them ideal for pressure vessels that operate under extreme conditions.
| 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. |
