The temperature ranges of embrittlement by the copper and lead fusions of the VNS55 high-durable stainless steels have been determined experimentally. For the temperature range of 293 to 1350 К they have set the corresponding numerical values of the characteristics of strength, ductility and durability of the steels in contact. The optimum structure-phase and chemical composition of steels have been defined by minimizing of the copper fusion embrittlement action, being the basis for the recommendation development for the production of advanced Brazed sandwich honeycomb structures with honeycomb of steel of 6 on.% of δ-feritte.

Keywords: stainless steel, lead, copper, weld-fabricated, cellular constructions.
