Overview of Cryogenic nickel plates

Cryogenic nickel plates are excellently suited to applications exposed to extremely low temperatures. They are used for the transport of liquefied natural gas (LNG) and liquefied petroleum gas (LPG).
A 645 Gr A / A 645 Gr B, cost reduction and increased safety in ethylene and LNG tank construction.
State-of-the-art production facilities make it possible for us to manufacture both steel grades A 645 Gr A and Gr B as well as conventional 5% and 9% nickel steels.

● LNG
Natural gas is liquefied at the extremely low temperature of -164 °C, shrinking its volume by a factor of 600. This makes its storage and transport possible and economically efficient. At these very low temperatures, the utilization of special 9% nickel steels is necessary in order to guarantee sufficient ductility and resistance to brittle cracking. We supply extra wide plates to this market segment, even in thicknesses up to 5 mm.

● LPG
The LPG process is used to produce propane and process gases from natural gas. These gases are liquefied at room temperature at low pressure and are stored in special tanks made of 5% nickel steels. We supply shell plates, heads and cones from a single source.

Take ASTM A 645 Gr B Plate For example

● Use of A 645 Gr A for the production of ethylene tanks provides roughly 15% higher strength, increased safety and the possibility of reduced wall thickness for substantial cost savings in tank construction.
● ASTM A 645 Gr B achieves material properties equivalent to those of traditional 9% nickel steels in LNG storage but meets these requirements with roughly 30% lower nickel content. A further result is substantially reduced costs in the production of onshore and offshore LNG tanks and in the construction of LNG fuel tanks.

Highest quality for the highest degree of security

The basis of our high-quality nickel plates are high-purity slabs from our own steelmaking plant. The very low carbon content guarantees perfect weldability. Further advantages are found in the product's excellent impact strength and the fracturing properties (CTOD). The entire plate surface undergoes ultrasonic testing. The residual magnetism is below 50 Gauss.

Preprocessing to meet specific customer requirements

● Sand-blasted or sand-blasted and primed.
● Preparation of welded edges: Minimal hardening of the burned edge is made possible by the low carbon content.
● Plate bending.
