ELECTRODO THERMANIT 25/22 H (E Z25 22 2 L B 2 2) - Cl - pitting - Ac. Nítrico Ø2,50mm x 3,50 Kg

25/22/2 electrode for urea, nitric acid and chlorides

Thermanit 25/22 H by voestalpine Böhler Welding is a basic, austenitic covered electrode of the modified E310Mo-15 type. It offers excellent corrosion resistance in strongly oxidizing and slightly reducing environments, against pitting and chloride-induced stress corrosion; it withstands seawater and nitric acid. In 2.50 mm it is ideal for thin sections and root passes.

Key advantages

  • Urea plants: designed for urea synthesis corrosion.
  • Chlorides and pitting: high resistance, seawater resistant.
  • Nitric acid: good resistance.
  • Scaling resistant up to 1050 °C.
  • Certified quality: TÜV and CE.

Applications

  • Urea synthesis plants and nitric acid service.
  • Steels 1.4335, 1.4435, 1.4465, 1.4466, 1.4577, UNS S31050, 316L and 725LN.
  • Surfacing of high-temperature steels.
  • Seawater and chloride environments.
