Korea Herald reported that South Korean steel maker POSCO announced that its high manganese steel which withstands extremely low temperatures has received technical approval from global energy firm ExxonMobil for usage in LNG storage tanks, a mandatory step for Posco to participate in the project that ExxonMobil invests in. POSCO official said “The approval process was shortened based on ExxonMobil’s trust in what we do and our technical prowess with experience of applying our new material to the fifth tank at LNG terminal in Gwangyang and some 20 LNG carriers globally.”POSCO & ExxonMobil formed a technical partnership in 2020 to expand the use of high manganese steel which POSCO succeeded in mass-producing for the first time in the world. As for the next step, POSCO will discuss with ExxonMobil the application of high manganese steel overseas LNG projects. The two firms will also collaborate in other eco-friendly business which involves development of hydrogen and Carbon Capture, Utilization and Storage technology.Cryogenic high manganese steel is a new type of material that POSCO has developed in 2013, by adding 10-27% of manganese to steel so it can endure high-pressure, extremely low temperatures and be more wear-resistant. It can also safety store LNG, which is kept at minus 162 degrees Celsius in its liquid state. Using cheap material like manganese also makes it price competitive. It was listed on the Korean Industrial Standards in 2014. It also received approval from the American Society for Testing and Materials in 2017 and from the International Organization for Standardization in 2018. In 2018, the material was certified to be used in fabricating onshore pressure vessels and LNG storage tanks for ships and also onshore LNG storage tanks in 2019. South Korea’s Ministry of Trade, Industry, and Energy granted approval in 2021POSCO and ExxonMobil had previously co-developed slurry pipes with High manganese steel eight years ago, as a result of technical cooperation for five years from 2012 to 2017. Slurry pipes are used to transport oil sands. At the time, both companies devoted themselves to develop welding technology and pipe manufacturing processes optimized for High manganese steel with joint research starting from the pipe production stage to the field testing stage. As a result of such cooperation, the two companies succeeded in mass-producing the product
