With excellent weldability, toughness, and impact resistance, they are perfect for pressure vessels and boilers that operate in sour service conditions, where reliability and safety are paramount.
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.
Process of Manufacturing : Hot-Rolled (HR)
