Oil & Gas
Ultra-deep offshore, acid gases, very deeply buried hydrocarbons at high pressures and temperatures are the challenges currently encountered in gas and oil exploration and production. To meet these challenges, Aperam's offers engineering companies an extensive range of alloys and superalloys that combine high mechanical properties at ambient and elevated temperatures, excellent corrosion resistance, particularly for the extraction of fluids with high contents of H2S, SO2, free sulphur, CO2, chlorides, etc.

Fasteners
- An extensive range of grades are available to meet the request of high corrosion resistant alloys combined with high temperature resistant properties.
LNG
Thanks to its near zero thermal expansion between liquid natural gas temperature (-163°C) and its low modulus of elasticity, specific INVAR MI13 is the key alloy for the manufacturing of the tanks of LNG carriers made according to the membranes GTT technologies NO96, but also for new Mark V. The low expansion and the good weldability are also key advantages for the production of LNG transfer lines made of pipe-in-pipe technology, allowing for the avoidance of any expansion compensation systems such as loops or bellows and inducing significant cost savings by reducing such capex as the construction of a jetty or the dredging of a seabed close to the port thanks to sub-sea pipe-in-pipe lay out.
