Aatir Steel, based in Cairo, Egypt, stands out as a leading manufacturer and supplier of SA 516 GR.60/70N NACE HIC Plates, catering to the rigorous demands of the oil & gas, petrochemical, and energy industries. Renowned for providing top-notch steel solutions, Aatir Steel focuses on corrosion-resistant plates specifically designed for sour service and environments prone to hydrogen-induced cracking (HIC). With cutting-edge production capabilities and a strong commitment to quality control and international standards, the company guarantees exceptional durability, safety, and performance in every plate. Aatir Steel’s SA 516 GR.60/70N NACE HIC Plates are globally recognized for their reliability in critical pressure equipment and structural components.
These plates are carbon steel pressure vessel plates that have been normalized to enhance their strength and toughness. Typically, their chemical makeup includes carbon (max 0.21–0.27%), manganese (0.55–1.20%), phosphorus (max 0.035%), and sulfur (max 0.035%), all tailored to meet the NACE MR0175/MR0103 standards. They undergo rigorous testing for HIC resistance, making them suitable for sour gas applications. Mechanically, Grade 60 boasts a minimum tensile strength of 415–550 MPa and a yield strength of 240 MPa, while Grade 70 offers tensile strength ranging from 485–620 MPa and a yield strength of 260 MPa, ensuring outstanding performance in high-pressure and corrosive settings.
| 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. |
