What is SA 516 GR.70N NACE HIC Plates?

These plates are primarily made from carbon, manganese, phosphorus, sulfur, and silicon, with carefully controlled microalloying elements to boost toughness and corrosion resistance. The “N” indicates that the plates are normalized, which enhances grain refinement, strength, and mechanical consistency. They provide excellent tensile and yield strength, impressive elongation, and outstanding impact toughness, even in low temperatures. Their microstructure is designed to resist brittle fracture and hydrogen-induced cracking in sour service conditions.

SA 516 GR.70N NACE HIC Plates Specifications

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)
