Cryogenic steels

High toughness down to -196° C

Cryogenic steels from Dillinger put you on the safe side for extremely low temperatures. They retain adequate Charpy V-notch toughness, and thus high resistance to brittle fracture, even in the temperature range down to -196° C. This makes them the perfect choice for gas-liquefaction plants, for example, and for the transportation and storage of liquefied gases, such as LNG and LPG.

The Dillinger range for your needs:

  • Dillinger supplies cryogenic steels in conformity to EN 10028, Part 4, or the ASME standards.

  • Non-alloy and low-alloyed low-temperature steels.

  • Nickel steels containing 1.5 to 3.5 % Ni (down to -105° C).

  • Nickel steels containing 5 to 9 % Ni (down to -100° C to -196° C).

Useful information on cryogenic steels:

A problem common to most steels is the fact that they become brittle, i.e. the toughness of the steel decreases, as temperature falls. This phenomenon occurs only to a reduced extent in cryogenic steels. Special alloying elements shift the steep loss of Charpy V-notch toughness under exposure to extreme cold to even lower temperature ranges.
