SA 516 GR.70N NACE HIC Plates are carbon steel pressure vessel plates made up of carbon, manganese, phosphorus, sulfur, and silicon, which work together to enhance strength and toughness. These plates boast excellent notch toughness and resistance to hydrogen-induced cracking, making them perfect for sour service environments. In terms of mechanical properties, they offer a tensile strength ranging from 485 to 620 MPa, a minimum yield strength of 260 MPa, and impressive elongation properties for added ductility. Thanks to normalized heat treatment, these plates show reliability even in low temperatures and high pressures, ensuring a long service life in demanding applications that require durability, toughness, and crack resistance.
| Grade | ASME SA 516 GR.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. |
