HIC Resistant Steel Sheets and Plates are specifically designed to excel in tough environments where hydrogen-induced cracking poses a serious risk. Crafted through advanced steelmaking techniques and careful rolling or normalizing processes, these plates boast a clean microstructure with minimal impurities. They meet rigorous HIC and SSC resistance standards, ensuring enhanced safety, durability, and long-lasting performance. With their outstanding weldability, consistent mechanical properties, and resistance to internal cracking, they are perfect for critical pressure-containing and structural applications in demanding conditions.
These plates are made with a carefully controlled chemical composition, featuring low carbon content, reduced sulfur and phosphorus levels, and optimized amounts of manganese and silicon. Techniques like calcium treatment and vacuum degassing are often employed to reduce inclusions and enhance cleanliness. On the mechanical side, these plates deliver impressive yield and tensile strength, excellent toughness, and stable hardness, all of which contribute to their resistance against hydrogen diffusion and crack growth. The refined grain structure not only boosts impact resistance but also ensures reliable performance during fabrication processes like welding, forming, and machining.
