ASME SA 516 GR.70 NACE Steel Plates – Boiler Plates for Sour Gas & Corrosive Service
Conquest Steel & Alloys supplies premium-quality ASME SA 516 GR.70 NACE Steel Plates, engineered for sour gas applications and environments exposed to hydrogen sulfide (H₂S). These plates undergo rigorous NACE MR0175 / MR0103 approval and HIC testing, ensuring excellent resistance against sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC).
With high strength, superior toughness, and reliable weldability, GR.70 NACE plates are ideal for pressure vessels, boilers, and storage tanks operating under corrosive conditions.
