Supranite NGR AS

Supranite NGR AS

Made of nuclear grade expanded graphite foils and ultra thin stainless steels, laminated in a multi-layer structure capable of withstanding high stresses. The graphite and stainless steel are bonded without glue by an exclusive physico-chemical process that gives outstanding cohesion. PMUC n°17-0214.
