ASME SA 516 Grade 60N Plates are premium-quality carbon steel plates designed primarily for use in welded pressure vessels where improved notch toughness is important. The "N" designation indicates that the steel has undergone Normalization, a heat treatment process that refines the grain structure to enhance the material's impact properties and ductility at low temperatures. These plates are specifically manufactured as fully killed, fine-grain steel, ensuring a high degree of internal soundness and uniformity across the entire plate thickness.

To meet the rigorous demands of "Sour Service" environments in oil and gas refineries, our SA 516 GR.60N plates are strictly compliant with NACE MR0175 / ISO 15156 and NACE MR0103 standards. These plates undergo specialized HIC (Hydrogen-Induced Cracking) and SSC (Sulfide Stress Cracking) testing to prevent structural failure caused by hydrogen absorption in acidic environments. Combined with superior Charpy V-Notch impact values, these plates offer the highest level of safety and longevity for pressure vessels, heat exchangers, and storage tanks operating under extreme chemical and thermal stress.

ASME SA 516 GR.60N NACE and MR 0103-0175 Plates Features

» Normalized Heat Treatment: The "N" status ensures a refined, uniform grain structure, which significantly enhances notch toughness and ductility for critical safety applications.
» NACE MR0175 / ISO 15156 Compliance: Specifically processed to resist Sulfide Stress Cracking (SSC) in environments containing hydrogen sulfide (H₂S), common in oil and gas production.
» Hydrogen-Induced Cracking (HIC) Resistance: Undergoes rigorous HIC testing to ensure the steel is free from internal cracks and blisters caused by hydrogen absorption in sour service.
» Superior Low-Temperature Toughness: Maintains high impact resistance at sub-zero temperatures (tested at -46°C or lower), making it ideal for vessels in cold-climate or cryogenic-adjacent service.
» Fully Killed Fine-Grain Steel: Produced as fully killed steel with a fine-grain practice to ensure maximum internal soundness and better weldability compared to standard carbon steels.
» High Weldability: Low carbon equivalent (CEQ) values ensure the material is easily weldable while maintaining the integrity of the heat-affected zone (HAZ) under industrial welding conditions.
» Stringent Mechanical Testing: Includes mandatory Charpy V-Notch impact tests, tensile tests, and through-thickness (Z-direction) testing to verify structural performance.
» Extended Service Life in Refineries: Complies with NACE MR0103 for downstream refinery environments, offering protection against aggressive corrosion and stress cracking.

ASME SA 516 GR.60N NACE and MR 0103-0175 Plates Detailed Specifications

Property	Specification
Grade	ASME SA 516 GR.60N 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.
