Aatir Steel stands out as a reliable manufacturer and supplier of SA 516 Gr. 70N NACE HIC Plates right in Cairo, Egypt. These top-notch carbon steel plates are crafted specifically for high-pressure and corrosive settings. They’re designed to meet the rigorous NACE MR0175/ISO 15156 standards for hydrogen-induced cracking (HIC) resistance, making them perfect for the oil and gas, petrochemical, and offshore sectors. With a strong focus on quality control, Aatir Steel guarantees outstanding mechanical properties, precise dimensions, and solid surface integrity. The SA 516 Gr. 70N NACE HIC Plates blend strength, toughness, and corrosion resistance, ensuring dependable performance in pipelines, pressure vessels, and storage tanks that operate under sour service conditions.
SA 516 Gr. 70N NACE HIC Plates are crafted from carbon steel with carefully controlled levels of carbon (≤0.28%), manganese (0.85–1.20%), phosphorus (≤0.025%), sulfur (≤0.025%), and silicon (0.15–0.40%). These plates boast a minimum yield strength of 290 MPa and a tensile strength ranging from 485 to 620 MPa. They are specifically designed to withstand hydrogen-induced cracking and sulfide stress corrosion cracking. Thanks to their fine-grained microstructure, they offer excellent toughness, weldability, and notch resistance, ensuring they remain durable and reliable in high-pressure, sour service environments typical in the oil, gas, and petrochemical industries.
| 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. |
