The NACE MR 0103/0175 HIC Boiler Sheet and Plates are crafted to withstand hydrogen-induced cracking (HIC) and are tailored for sour service applications. The typical chemical makeup includes carbon (≤0.20%), manganese (0.90–1.60%), phosphorus (≤0.025%), and sulfur (≤0.005%), along with additional elements like chromium, molybdenum, and nickel to boost corrosion resistance. These plates boast impressive mechanical properties, featuring tensile strength between 485–620 MPa, yield strength of at least 260 MPa, and elongation of 22% or more. The steel undergoes thorough testing to ensure it meets NACE standards, making it perfect for high-pressure and corrosive environments.
