Phanuphong Steel, a prominent manufacturer and supplier of steel plates based in Bangkok, Thailand, has earned a stellar reputation for providing top-notch industrial-grade plates. Among their standout products are the **SA 516 GR.70N NACE HIC Plates**, meticulously designed to comply with rigorous international standards. These plates are specifically crafted for environments that are susceptible to hydrogen-induced cracking, making them a perfect fit for critical industries. With a strong commitment to durability, reliability, and customer satisfaction, Phanuphong Steel guarantees that their SA 516 GR.70N NACE HIC plates deliver exceptional performance across the oil, gas, and petrochemical sectors globally.
The SA 516 GR.70N NACE HIC plates are primarily made up of carbon, manganese, phosphorus, sulfur, and silicon, along with carefully controlled microalloying elements that enhance their strength. They boast impressive toughness, weldability, and corrosion resistance, even in the toughest operating conditions. These plates undergo a normalization process to refine their grain structure and boost durability. They provide a minimum tensile strength ranging from 485 to 620 MPa and a yield strength of about 260 MPa, along with remarkable notch toughness. Their resistance to hydrogen-induced cracking makes them particularly well-suited for sour service environments where reliability is paramount.
| 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. |
