Product Details
NACE & HIC tested boiler plates are high-quality pressure vessel steel plates designed for use in sour service environments where hydrogen sulfide (H₂S) is present. These plates are tested for Hydrogen-Induced Cracking (HIC) and comply with NACE MR0175 / MR0103 standards to ensure safe, reliable operation under highly corrosive conditions.
These plates are ideal for welded pressure vessels, storage tanks, and heat exchangers in industries like oil & gas, petrochemical, refinery, and offshore energy.
