Supplying consistent and high-performance steel solutions for various demanding applications.
SA 516 GR.65N NACE HIC Plates are high-strength pressure vessel plates specially designed for hydrogen-induced cracking (HIC) and sulfide stress corrosion environments. They meet NACE MR 0103/0175 standards, providing superior durability and resistance to harsh environments. These possess Carbon (≤0.26%), Manganese (0.85-1.20%), Silicon (0.15-0.40%), Phosphorus (≤0.025%), and Sulfur (≤0.015%) which impart excellent mechanical strength and durability. Used abundantly in petroleum and gas, petrochemical, and electricity sectors, they provide safety where there is presence of hydrogen sulfide.
| 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. |
