02Х21Н25М5ДБ, ЭК5 tape, sheet, round, wire

General characteristics

Stainless steel, 10−14 consist of carefully selected chemical elements. Depending on the composition and the presence in the alloy of those or other components, such raw materials are, as a rule, has a range of useful qualities, urgently demanded by modern industry. Alloy 02Х21Н25М5ДБ (ЭК5), due to the high content of chromium and Nickel, complemented by successfully balanced composition of a number of alloying substances, characterized by high physical and mechanical characteristics, heat resistance and excellent resistance to corrosion in aggressive environment.
