What is Boiler Plate Grade ASTM SA 516 GR.65N NACE

Boiler Plate Grade:- ASTM SA 516 GR.65N NACE is a high-quality carbon steel plate designed for use in pressure vessels and boilers, particularly in applications exposed to harsh conditions with the presence of hydrogen sulfide (H₂S). These plates are engineered to offer resistance to Hydrogen-Induced Cracking (HIC) and Sulfide Stress Cracking (SSC) and meet the standards set by the National Association of Corrosion Engineers (NACE).

• HIC & SSC Resistance:
  The SA 516 GR.65N plates are specifically designed to withstand hydrogen-induced cracking and sulfide stress cracking, making them suitable for sour service applications in corrosive environments.

• NACE Compliance:
  These plates adhere to NACE MR0175/ISO 15156 standards, ensuring they are suitable for use in environments with high concentrations of hydrogen sulfide, such as those found in the oil and gas industry.

• Intermediate Strength:
  SA 516 GR.65N offers a balance between strength and toughness, providing higher strength than SA 516 GR.60N and slightly lower than SA 516 GR.70N. This makes it versatile for a range of pressure vessel and boiler applications.

• Low-Temperature Toughness:
  The plates maintain excellent toughness at low temperatures, ensuring reliability and performance in both high- and low-temperature conditions.

• High Weldability:
  SA 516 GR.65N plates are easily weldable, which is crucial for the fabrication and construction of large pressure vessels, boilers, and storage tanks.
