Filiz Steel, based in Istanbul, Turkey, is a reputable manufacturer and exporter of SA 516 GR. 60/70N NACE HIC plates, specifically crafted for environments rich in hydrogen sulfide and sour service. These plates undergo rigorous testing for Hydrogen Induced Cracking (HIC) resistance and adhere to NACE MR 0103 and MR 0175 standards, making them perfect for critical applications in the oil, gas, and petrochemical sectors. With a normalized heat treatment (“N”) that enhances mechanical toughness and microstructure, Filiz Steel guarantees that each plate meets strict international quality standards, ensuring they are ready to perform in tough operating conditions.
SA 516 GR. 60/70N NACE HIC plates are carbon steel pressure vessel plates with precisely controlled chemical compositions to resist hydrogen-induced damage. Their typical makeup includes Carbon (≤0.27%), Manganese (0.79–1.60%), Phosphorus (≤0.020–0.030%), Sulfur (≤0.010%), and Silicon (0.13–0.45%). Grade 60 boasts a minimum yield strength of 220 MPa and a tensile strength ranging from 415 to 550 MPa, while Grade 70 offers a yield strength of 260 MPa and tensile strength between 485 and 620 MPa. Each plate is subjected to thorough HIC testing and is normalized to improve notch toughness and prevent embrittlement in sour gas environments.
| Grade | ASME SA 516 GR.60/70N 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. |

These SA 516 GR. 60/70N NACE HIC plates find extensive use in industries where resistance to hydrogen-induced cracking is essential, such as oil refineries, offshore platforms, chemical plants, and natural gas processing facilities. They are particularly well-suited for manufacturing pressure vessels, columns, heat exchangers, and storage tanks that operate in environments with wet hydrogen sulfide (H₂S). Thanks to their exceptional resistance to cracking and corrosion, these plates significantly reduce the risk of failures and minimize maintenance downtime.
SA 516 GR.60/70N NACE HIC Plates are mainly applied in high-hydrogen-induced cracking and corrosion-resistant industries. The plates are best suited for the production of pressure vessels, storage tanks, heat exchangers, and boiler parts in severe environments. The primary industries that use these plates are oil and gas, petrochemicals, power generation, chemical processing, and offshore platforms. Their improved mechanical properties and durability make them a must in hydrogen sulfide and corrosive environment applications to provide long-lasting performance and safety.
