CryElso® 9Q is an alloyed steel grade containing 9% nickel intended for the fabrication of Liquefied Natural Gas storage tanks and welded pressure vessels designed for extra low temperature service. CryElso®9Q is a Quenched and Tempered grade, to provide better tensile and toughness properties. CryElso® 9Q is manufactured via the electric arc furnace basic process, with dephosphorisation, followed by ladle refining with desulfurisation and vacuum degassing in order to provide reproducible chemistry, clean and homogeneous steel.

The use of special steelmaking practice provides high cleanliness combined with optimised chemical composition.

CryElso® 9Q produces an excellent toughness at very low temperature and very good crack arrest properties.

CryElso® 9Q has been extensively supplied for LNG storage tanks projects worldwide. CryElso® 9Q is recognised by all the world-renowned engineering companies as a steel grade suitable for the construction of very safe Liquefied Natural Gas storage tanks.

It is further optimised for use in pressure vessels applications, cryogenic piping and ship board storage systems.
