What is BQ Plate Grade SA 516 GR.70N NACE

BQ Plate:- Grade SA 516 GR.70N NACE plate is a carbon steel plate designed for use in pressure vessels and boilers operating in corrosive environments. These plates are particularly suited for applications where resistance to Hydrogen-Induced Cracking (HIC) and Sulfide Stress Cracking (SSC) is critical. BQ plates comply with NACE (National Association of Corrosion Engineers) standards and ensure long-lasting performance in sour service conditions, typically in oil, gas, and petrochemicals.

• HIC & SSC Resistance:
  The plate is engineered to resist hydrogen-induced cracking and sulfide stress cracking, making it suitable for use in environments containing hydrogen sulfide (H₂S), such as sour gas fields.

• NACE Compliance:
  Fully compliant with NACE MR0175/ISO 15156 standards, ensuring reliable performance in sour service environments where corrosion is a major concern.

• Moderate Strength:
  SA 516 GR.70N provides good mechanical strength and toughness, making it ideal for medium-pressure applications where both durability and corrosion resistance are needed.

• Low-Temperature Toughness:
  These plates offer excellent toughness at low temperatures, making them suitable for both low- and high-temperature applications.

• High Weldability:
  SA 516 GR.70N plates are easily weldable, which is crucial for the fabrication of large industrial equipment such as pressure vessels and storage tanks.
