Shalan Steel, a top-notch manufacturer and supplier located in Kuala Lumpur, Malaysia, specializes in high-quality SA 516 GR.70N NACE HIC Plates. These plates are specifically designed for demanding pressure vessel and boiler applications in sour service and corrosive settings. They undergo a normalization process to boost toughness and meet NACE MR0175 standards, which guarantees outstanding resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion. With a focus on strict quality control and precision manufacturing, SA 516 GR.70N NACE HIC Plates deliver excellent weldability, durability, and consistent mechanical strength, making them perfect for the oil, gas, petrochemical, and offshore industries where safety and longevity are crucial.
The makeup of SA 516 GR.70N NACE HIC Plates features carefully balanced levels of carbon, manganese, silicon, phosphorus, and sulfur, along with microalloying elements that enhance strength and cracking resistance. The normalization process fine-tunes the grain structure, improving ductility, notch toughness, and performance in low temperatures. These plates boast high tensile strength, remarkable resistance to hydrogen blistering and stepwise cracking, and dependable structural integrity even under high pressure and harsh environmental conditions.
| 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. |
