On April 5, 2022, JGJT, a leading stainless steel technology company in China, developed a high-temperature resistant molten salt stainless steel for photothermal power generation, which meets customer requirements for quality control. It has achieved a total supply of over 200 tons and significantly improved its molten salt corrosion resistance, reaching an international leading level.
This corrosion-resistant stainless steel belongs to high carbon niobium containing Cr-Nb/Niobium austenitic stainless steel. Due to the stable element niobium, it has good intergranular corrosion resistance, high high-temperature strength, and good high-temperature oxidation resistance.
High carbon Nb containing Cr Nb/Niobium austenitic stainless steel is widely used in the field of molten salt storage tank manufacturing of optical thermal power station.
