Steels for cryogenic service

Advantages
Applications

The CryElso® family includes a complete range of cryogenic steel grades from 0.5%Ni to 36%Ni steels, designed for the storage and transport of gases from propane to LNG.

Industeel’s CryElso® range offers the best balance between strength, toughness and weldability for these low-temperature applications, with special attention paid to crack arrest properties thanks to a special steelmaking process.

CryElso® products can be supplied in wide range of dimensions starting from 5 mm thickness up to very high unit weights.

Cryogenic storage and transport of liquefied gases demand the highest level of safety, a criteria that is fully satisfied by the steels used in these applications.

LNG – Storage & transport

Examples of applications

  • 9%Ni for LNG storage tanks up to 200.000m3 capacity
  • 9%Ni steel for 304L steel pipes for LNG transport (jetty to tank)
  • 9%Ni hulls for GBS, FLNG structures
