Recently, Chinese high-performance steel manufacturer HNHL has successfully produced high-manganese steel for low-temperature pressure vessels, with various properties meeting customer needs.
Among them, the ultra-low temperature impact performance is excellent, reaching three times that of the national standard. Even in the ultra-low temperature environment of minus 200 degrees Celsius, it can remain stable and is an ideal material for manufacturing LNG fuel storage tanks.
LNG carrier is an internationally recognized "three-high" product. LNG carrier is a special ship that transports liquefied gas at a low temperature of minus 163 degrees Celsius (-163 °C). The "jewel in the crown" can only be built by more than 10 shipyards in the United States, China, Japan, South Korea and a few countries in Europe.
The high manganese steel developed by HNHL has good low temperature resistance and wear resistance. Compared with the 9% nickel steel most commonly used in LNG fuel storage tanks, the 24% manganese steel has the advantages of abundant output and stable price, which will greatly reduce the Shipbuilding costs for LNG ships.
