POSCO's newly developed high-manganese steel is expected to be used in an LNG-fueled bulk carrier that is under construction at Hyundai Mipo Dockyard.
According to a POSCO official, Thursday, the steelmaker's manganese steel will be provided for the carrier beginning in the third quarter of this year. The bulk carrier is expected to be completed late next year and then it will transport limestone used by POSCO from Gangwon Province to the company's steel plants in Gwangyang.
The LNG-fueled bulk carrier has a 50,000-ton cargo capacity and can carry more than seven times the capacity of other bulk carriers.
The steel is about 20 percent manganese, capable of storing and carrying ultra-low-temperature LNG at minus 162 degrees Celsius. It also has a stronger yield strength and cryogenic toughness than the alloy materials used for similar tanks including nickel and aluminum, in addition to being less expensive as well, an official said.
"POSCO's high-manganese steel will lead the market with its value," said an official.
"The LNG-fueled bulk carrier is being built under international standards and codes. Once it proves its market competitiveness, high-manganese steel will be used more and more as a material for ultra-low-temperature environments in the industry."
