Recently, the contract for the 9Ni steel used in the high-end ultra-low temperature storage tanks of the LNG storage and distribution station project in the Taiyuan Steel Fujian-Guangdong Economic Cooperation Zone was successfully finalized, with all acceptance criteria meeting international advanced standards. The successful completion of this supply guarantee task marks a new improvement in the quality level of such products produced by the company, thus writing a new chapter in the history of 9Ni steel used for ultra-low temperature storage tanks at Taiyuan Iron and Steel Group – from its initial introduction and use in China to achieving high standards and sustainable development. 9Ni steel used for ultra-low temperature storage tanks is primarily employed in the manufacture of liquefied natural gas (LNG) storage tanks and transport vessels. It is required to operate continuously at temperatures as low as -162°C for over 50 years, with a minimum operating temperature of up to -196°C. It features high strength, excellent low-temperature toughness, and good weldability, making it the material with the best toughness for use in extreme cold environments. However, due to its complex manufacturing process, it is considered one of the steels with the highest technical requirements and greatest production difficulties in the industry. For a long time, our country relied entirely on imports. In 2007, with the strong support of the **\"863 Program\" and the \"11th Five-Year Plan for Scientific and Technological Support,\" Taiyuan Iron and Steel Company, in collaboration with relevant organizations and research institutions, successfully overcame key technical challenges and achieved industrial-scale production. This material was then applied in projects carried out by companies such as CNPC, CNOOC, and Shaanxi Yanchang Petroleum, making the company the first in China to develop and use this material. In 2011, the technology for manufacturing 9Ni steel for ultra-low temperature storage tanks at Taiyuan Iron and Steel Company won the first prize in the Metallurgical Science and Technology Award. Over the years, the technical team at Taiyuan Iron and Steel Company has continued to explore and conduct in-depth research, focusing on improving aspects such as the purity of the steel and its surface quality. They have gradually developed advanced manufacturing processes such as ultra-pure smelting techniques and heat treatment methods, resulting in steel of ultra-pure quality. The steel’s ultra-low temperature impact strength is among the best in the world, and its overall physical properties are at an internationally advanced level. A set of proprietary technologies with independent intellectual property rights has been developed, which has significantly contributed to the improvement of the manufacturing standards and quality control for 9Ni steel used in ultra-low temperature storage tanks in China. The LNG storage and distribution station project in the Fujian-Guangdong Economic Cooperation Zone is designed to support the energy supply needs of Chaozhou City and this economic cooperation zone. It not only helps to optimize Chaozhou’s energy structure and ensure a steady gas supply for eastern Guangdong and surrounding areas, but it also serves as an important source of gas for emergency peak-shaving within the \"Guangdong Province Gas Network.\" It is a vital infrastructure project that enhances the reliability of natural gas supply and improves the living standards of residents. The team leader stated that following the LNG storage and distribution station project in the Fujian-Guangdong Economic Cooperation Zone, Taiyuan Iron and Steel Group has recently won the bid for a 160,000-cubic-meter LNG storage tank project in Tangshan owned by PetroChina. The first batch of supplies has been delivered and has passed user inspection.
