Chetan Steel is a prominent manufacturer and supplier of SA 516 Gr.70N NACE HIC Plates based in Delhi, providing top-notch pressure vessel steel designed for critical and corrosive service applications. With a strong focus on quality control and adherence to standards, Chetan Steel delivers plates that comply with ASME guidelines and meet NACE and HIC resistance criteria. These plates undergo a normalization process to enhance their toughness and reliability. Catering to sectors like oil & gas, petrochemicals, refineries, and power plants, Chetan Steel guarantees consistent quality, tailored dimensions, and prompt delivery for demanding industrial projects.
SA 516 Gr.70N NACE HIC Plates are crafted from low-carbon steel, with carefully controlled additions of manganese, silicon, and other alloying elements to boost strength and toughness. The normalization process helps achieve a uniform grain structure and improves mechanical properties. These plates exhibit excellent tensile and yield strength, high impact toughness, and outstanding resistance to hydrogen-induced cracking (HIC). Additionally, the material offers good weldability and stability under high pressure and temperature conditions.
