Thabiso Steel stands out as a top-notch manufacturer and supplier located in Cape Town, South Africa, specializing in high-quality SA 516 Gr. 65N NACE HIC Plates. These plates are meticulously designed for use in pressure vessels, boilers, and storage tanks that operate in sour environments with hydrogen sulfide, where it’s crucial to have resistance against hydrogen-induced cracking (HIC) and sulfide stress corrosion. Adhering to the rigorous NACE MR0175/ISO 15156 standards, Thabiso Steel guarantees that each plate delivers exceptional strength, toughness, and durability, making them a dependable choice for critical industrial applications in tough conditions.
The SA 516 Gr. 65N NACE HIC Plates are primarily made up of carbon, manganese, phosphorus, sulfur, and silicon, with careful microalloying to boost toughness and HIC resistance. The “N” signifies that these plates undergo normalized heat treatment, which refines their grain structure and ensures consistent mechanical properties. They boast impressive tensile and yield strength, high elongation, and remarkable impact toughness even at low temperatures. Thanks to their chemical makeup and fine-grained microstructure, they offer excellent protection against brittle fracture and hydrogen-induced cracking in sour service environments.
| Grade | ASME SA 516 GR.65N 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. |
| Process of Manufacturing | Hot-Rolled (HR) |
