JISCO has achieved a breakthrough in special steel rolling technology, successfully mass-producing 347H stainless steel plates (8mm × 2600mm) for molten salt storage tanks used in concentrated solar power (CSP) plants. Known as the "energy storage heart" of CSP facilities, high-temperature molten salt tanks demand exceptional heat and corrosion resistance. JISCO's self-developed 347H stainless steel delivers outstanding high-temperature strength, oxidation resistance, and intergranular corrosion resistance, reducing weld seams to enhance structural safety and service life of thermal energy storage equipment, supporting the large-scale growth of China's CSP industry.
