ASME SA 516 GR.70 NACE + HIC Steel Plates – Sour Service & Boiler Applications
Conquest Steel & Alloys is a leading supplier of ASME SA 516 GR.70 NACE + HIC Steel Plates, engineered for sour service applications and pressure vessels in the oil, gas, and petrochemical industries. These plates are specially manufactured to be NACE MR0175 compliant and HIC-tested, ensuring maximum safety and performance in environments exposed to hydrogen sulfide (H₂S).
The plates combine high tensile strength, notch toughness, and excellent weldability with resistance to sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC), making them highly reliable in critical boiler and pressure vessel applications.
