Cryogenic steel plates
Equipment for the production, storage and transport of low-temperature gases such as LPG, ethylene and LNG must be made of materials that do not become brittle at temperatures commonly reaching -60 to -170°C.
For this reason, Industeel has developed its CryElso® family of high toughness nickel alloyed steels specially designed for low temperature applications. They have a low carbon content for enhanced weldability and offer improved crack arrest properties for greater safety.
Applications
- CryElso® 9 - 9%Ni alloyed
- Applications: On-ground and Floating LNG Storage Tanks, low temperature pressure vessels, cryogenic piping
