POSCO’s cryogenic high manganese steel was recently registered as a standard technology with the American Society for Testing and Materials (ASTM), an organization that tests and researches all materials, including metals and non-metals, and develops and publishes technical standards. So far, more than 30,000 experts from 140 countries have registered more than 12,000 technical standards. The technologies registered with ASTM are used as standards or specifications for engineers not only in the U.S., but globally. Its registration with ASTM means that POSCO’s cryogenic high manganese steel is recognized as a material that can be safely used all around the world.
The cryogenic high manganese steel is a high value-added material that POSCO proprietarily developed after more than a decade of research. It is the representative World Premium Product of POSCO. Cryogenic high manganese steel is a steel product that can withstand a very low temperature of -196℃, making it suitable for storing and transporting Liquefied Natural Gas (LNG). Also, because it is more weldable than conventional nickel alloy steel and 20-30% cheaper than nickel alloy steel, stainless steel and aluminum alloy steel, it is a solid alternative to these competing materials.
POSCO is constantly striving to develop and commercialize new steel products. Its recent registration with ASTM International strengthens its competitiveness in advanced steel technology. Teresa Cendrowska, VP of Global Cooperation at ASTM International stated, “POSCO is leading the standardization of new steel technologies at ASTM International and has become a model for other steelmakers by setting a new standard for high manganese steel.”
Last year, POSCO’s cryogenic high manganese steel was used for an LNG fuel tank for the world’s largest LNG-fueled bulk carrier (a bulk carrier using LNG as fuel) built by Hyundai Mipo Dockyard. In the future, POSCO plans to provide Solution Marketing to domestic and overseas oil majors and EPC customers. It also plans to sell World Premium Products in the energy sector and develop new markets.
