NACE MR 0103/0175 HIC Boiler Sheets and Plates are made from a blend of carbon, manganese, silicon, phosphorus, sulfur, and trace alloying elements, all optimized for strength and crack resistance. These plates undergo thorough testing to guarantee low impurity levels and remarkable toughness. They boast high tensile strength, solid yield strength, and excellent impact resistance, even in challenging environments. With outstanding resistance to hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC), they reliably perform in sour gas and petrochemical settings, adhering to NACE standards for safety, durability, and performance.
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)
