Sayed Steel, a well-respected manufacturer and supplier based in Safat, Kuwait, specializes in high-quality SA 516 GR.70N NACE HIC Plates. These plates are specifically designed for tough sour-service and hydrogen-rich environments. They undergo a normalization process to enhance toughness and are rigorously tested for hydrogen-induced cracking, ensuring they perform reliably in refineries, petrochemical plants, and high-pressure processing systems. Sayed Steel follows the NACE MR0175/ISO 15156 standards, which guarantees excellent corrosion resistance, weldability, and consistent mechanical performance. With cutting-edge production capabilities and a strong focus on quality control, the company provides durable, high-performance plates that meet the critical needs of the oil and gas, chemical, and energy sectors.
The SA 516 GR.70N NACE HIC Plates are made with carefully controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur to achieve the best possible strength, ductility, and corrosion resistance. The normalization process refines the grain structure, leading to improved toughness and better resistance to hydrogen cracking. These plates boast high tensile and yield strength, outstanding notch toughness, and stable mechanical properties, even in harsh conditions. Their mechanical profile supports reliable welding, forming, and fabrication, making them perfect for pressure vessels and equipment that come into contact with hydrogen sulfide and other corrosive substances.
| 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. |
