NACE MR 0103/0175 HIC-resistant steel is formulated with precise amounts of carbon, manganese, sulfur, and phosphorus, along with micro-alloying elements to minimize hydrogen embrittlement. This material boasts remarkable crack resistance, impressive toughness, and consistent strength in sour service conditions. It retains high tensile strength, solid yield strength, and excellent impact values, even in challenging environments. The steel undergoes specialized processing to enhance its resistance to hydrogen blistering, HIC, and sulfide stress cracking. Additionally, it offers good weldability and structural stability, making it an ideal choice for pressure vessels and boiler systems that handle corrosive media.
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)
