What is SA 516 GR.65N NACE and MR 0103-0175 Plates?

SA 516 GR.65N is a carbon steel plate grade designed primarily for moderate to lower-temperature service in pressure vessels. It features a carbon content of 0.18–0.26%, along with manganese (0.85–1.20%), silicon, phosphorus, and sulfur, all kept within controlled limits. When the steel is normalized (indicated by “N”), it gains enhanced notch toughness. Plates that are certified to NACE MR0103 and MR0175 are specifically engineered to resist sulfide stress cracking (SSC), which is crucial in sour gas environments. These specifications ensure that the material is well-suited for areas with H₂S exposure. The mechanical properties include a minimum yield strength of 240 MPa and tensile strength that ranges from 450–600 MPa, depending on the thickness.

SA 516 GR.65N NACE and MR 0103-0175 Plates Specifications

Grade	ASME SA 516 GR.65N 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)
