Bohler Thermanit 25/22 H (Austenitic Steel) Stainless Steel Stick Electrodes
Bohler Thermanit 25/22 H are premium, high alloyed fully austenitic stainless steel filler metal, engineered for joining & overlay welding in highly aggressive corrosive environments. Specially designed to handle the highly punishing ammonium carbonate environments found in chemical processing. Ideally suited for welding matching or similar fully austenitic stainless steels, such as 1.4465 (X1CrNiMoN25-22-2) or UNS S31050.
Features
- High-quality corrosion-resistant claddings and overlays on unalloyed or low-alloyed base steels.
- Offers exceptional safeguarding against inter-granular corrosion (IGC), selective corrosion, and chloride-induced pitting and stress corrosion cracking (SCC).
- It maintains a maximum stable operating threshold up to 350°C.
- Formulated to ensure clean, high-purity deposits that minimise the vulnerability to hot-cracking—a typical risk associated with fully austenitic structures
