Serving the growing industrial landscape of Addis Ababa and across Ethiopia, Desta Steel proudly supplies essential materials built to withstand demanding environments. Our focus includes the specialized SA 516 GR.65N NACE HIC plates, which are engineered for superior performance. These plates are specifically designed to resist the corrosive threat of hydrogen-induced cracking, making them a critical and reliable choice for critical projects in the oil, gas, and petrochemical sectors, where both high pressure and corrosive elements are a constant challenge.
The composition of these plates is carefully controlled, with specific limits on elements like sulfur and phosphorus, and the inclusion of elements like copper and nickel to enhance corrosion resistance. Mechanically, they offer a minimum yield strength of 240 MPa and a tensile strength ranging from 450 to 620 MPa. This balance of chemistry and robust mechanical properties ensures exceptional toughness and dependable structural integrity under high-stress conditions.
| 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) |
