Invar is a low expansion alloy especially adapted to cryogenic conditions which is used in the construction of a double layer lining of the tanks in which LNG is transported.
ArcelorMittal said the contract confirmed the market leadership of the company, formerly known as Imphys, in the supply of its alloy to the carrier market.
Invar M93TM constitutes the benchmark in the gas carrier market. ArcelorMittal Stainless & Nickel Alloys has more than 90 percent share of the niche market.
The alloy is seen as offering physical and mechanical properties that contribute to the increased service life of LNG carriers, which are being built ever larger to transport the product further as the market expands.
