Thabiso Steel is a well-respected manufacturer and supplier located in Cape Town, South Africa, specializing in top-notch SA 516 Gr. 60/70N NACE HIC Plates. These plates are crafted specifically for pressure vessel and boiler applications that require outstanding resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion. Thabiso Steel is committed to following international NACE standards and employing advanced heat treatment processes to ensure top performance. Known for their excellent weldability, strength, and toughness, SA 516 Gr. 60/70N NACE HIC Plates are perfect for tough and corrosive environments.
These plates are made from a mix of carbon, manganese, phosphorus, sulfur, and silicon, along with additional elements that enhance their resistance to hydrogen-induced cracking. They boast high tensile and yield strength, impressive impact toughness, and great elongation, even in low temperatures. The “N” signifies that they undergo normalized heat treatment, which improves mechanical uniformity and structural stability. Their fine-grained microstructure guarantees reliable performance under high pressure, in corrosive settings, and across varying temperature conditions.
| 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. |
