Applications
By liquefying natural gas (LNG) at -164 °C its volume is reduced by a factor of more than 600, thus making handling and
storage easier and more economical. At these extremely low temperatures standard ferritic structural steels are not suitable anymore, due to lack of sufficient toughness and the risk of brittle fracture. 9% nickel steels achieve the mechanical
properties required for building storage tanks and cryogenic pipes used for loading and unloading of LNG tankers and
offer a reliable structural integrity down to -196 °C.
LPG (liquified petroleum gas) is liquified at ambient temperature under low pressure. It is stored and transported in special tanks made of 5% nickel steels. For those tanks installed on ships we deliver shell plates and heads from a single
source.

Quality made by voestalpine Grobblech
The basis for the production of high-quality nickel steel plates are excellent slabs.
We use continuously cast slabs from our top steel mill at voestalpine Stahl GmbH in Linz.
Pure steel
Nickel steels with high purity are produced by LD-process (Linz-Donawitz-process, invented by engineers of
voestalpine) with subsequent metallurgical and vacuum treatment. Especially for 9% nickel steels we provide
ultra low levels of phosphorus, sulphur and carbon.

Excellent toughness and improved CTOD-values
Our nickel steels provide excellent fracture mechanics test results. The required values in the crack tip opening displacement (CTOD) test were overchieved by far.

100% US testing online
Ultrasonic testing is done online and covers 100% of the plate surface.
Residual magnetism below 50 Gauss is guaranteed.
Prefabrication
Nickel steel plates can be offered in prefabricated condition:
shotblasted or shotblasted & primered
weld edge preparation: the ultra low carbon content of our Nickel
steel plates provides low hardening of the weld edges
bending of the plates
