NACE MR 0103/0175 HIC Boiler Sheets and Plates are carbon steel plates that are carefully alloyed with controlled amounts of carbon, manganese, sulfur, phosphorus, and occasionally micro-alloying elements like niobium and vanadium. They undergo special processing to achieve low sulfur content and high cleanliness, making them resistant to hydrogen-induced cracking and sulfide stress corrosion cracking. These plates boast excellent toughness, impressive tensile strength, and consistent impact properties, even in challenging service conditions. They comply with rigorous NACE standards for sour service applications, ensuring reliability in corrosive and hydrogen-rich environments.
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)
