Crossing the sea at -164° C

Now that its 9% nickel steel has been approved, steel is now certified with two more important classification organizations.

The coldest location inhabited by humans has a temperature of 68° Celsius. This temperature was measured in a village in the Sakha Republic, a federal subject of Russia. At this temperature everything freezes to ice. By contrast, natural gas liquefies when the temperature drops much further to -164° Celsius.

The liquefaction of natural gas into LNG (Liquefied Natural Gas) enables gas to be transported and stored in tanks. The advantage? In liquid form, natural gas has 600 times less volume than in gas form. The pressure tanks require high-quality, low-temperature, 9%-nickel steels that remain tough even at temperatures of -196° Celsius.

LNG tanker with spherical tanks: Natural gas can be transported by ship in its liquid state.

The material produced by the Steel division of thyssenkrupp has been approved by both major maritime classification organizations, Bureau Veritas and Lloyd’s Register. The certifications are required before a company can even begin to be considered as a supplier for a shipbuilding project. For customers this means greater flexibility when making decisions. For Duisburg, the certifications open up additional sales opportunities for heavy plate with a maximum thickness of 50 millimeters.
