Witness the decade-long rapid development of chemical processing equipment; praise the prosperity and strength of modern China. Replies will be rewarded – discussions are welcome. ------------------------------------------- In November 2022, Jiugang Group, in collaboration with Lansi Group, successfully developed N08810 high-temperature corrosion-resistant alloy steel plates. The structure of these materials as well as their various properties meet the requirements for use in core components of photovoltaic polysilicon production, thus establishing a complete industrial chain for these critical materials in the field of new energy. The N08810 high-temperature corrosion-resistant alloy steel plate belongs to the high-nickel heat-resistant alloys; it exhibits excellent strength, corrosion resistance, oxidation resistance, and high structural stability at high temperatures, and is primarily used in cold hydrogenation reactors for new energy photovoltaic polysilicon production. N08810 high-temperature corrosion-resistant alloy steel plates have extremely high requirements regarding purity, microstructure, and properties; their heat treatment processes are demanding, making industrial production difficult. Jiugang Group and Lansi Group formed R&D teams and leveraged their respective equipment advantages; after more than 7 months of development, the first batch of products passed the tests and met the standard requirements. At the same time, both parties are focusing on the key materials used in polysilicon equipment within the photovoltaic industry, and are carrying out technical research on N08120, a high-temperature corrosion-resistant alloy steel sheet that serves as material for the next generation of polysilicon cold hydrogenation reactors with improved performance. The successful development of the N08810 high-temperature corrosion-resistant alloy steel plate is a concrete example of strong collaboration among provincial state-owned enterprises, providing an important foundation for the upgrading and transformation of the region’s industries toward higher levels of sophistication. It also enhances the province’s overall competitiveness in the field of high-end energy equipment manufacturing.
