| 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. |

SA 516 Gr.65N HIC plates are crafted from high-strength carbon steel, specifically tailored for boilers and pressure vessels. They boast excellent notch toughness and are resistant to hydrogen-induced cracking (HIC). The typical chemical makeup includes carbon, manganese, phosphorus, sulfur, silicon, and a few trace alloying elements, all optimized for strength and weldability. On the mechanical side, these plates deliver high tensile and yield strength, good elongation, and remarkable impact toughness, even in low temperatures. The “N” grade signifies that they undergo normalized treatment, which boosts toughness and minimizes the risk of HIC, making them ideal for sour service environments.
You’ll find SA 516 Gr.65N HIC plates widely used in industries where safety and reliability under high-pressure conditions are paramount. They play a crucial role in the fabrication of boilers, pressure vessels, heat exchangers, and storage tanks. In the oil and gas industry, they are particularly suited for sour gas and petrochemical processing equipment due to their resistance to hydrogen-induced cracking. Moreover, these plates are utilized in power generation plants, chemical plants, and various industrial manufacturing facilities that demand high-strength carbon steel with excellent weldability and toughness. Their durability ensures they provide a long service life, even in the most challenging operational environments.
