Bohler Thermanit 690 (Corrosion Protection) NiCr alloys Stick Electrodes
Ni-base stick electrodes for joining high corrosion resistant steels with resistance in oxidising media like nitric acid, primarily for industries in nuclear power engineering -frequently used for welding steam generator tubing and components exposed to high-temperature pure water environments, chemical & petrochemical processing - deal for nitric acid production plants and vessels handling highly concentrated oxidising chemicals.
Features
- High resistance to stress corrosion cracking in pure water environments and resistance in oxidising media e.g. nitric acid.
- Excellent mechanical stability and high-temperature oxidation resistance, making it suitable for aggressive chemical processing conditions.
- The basic coating delivers high metallurgical purity, clean weld beads, and excellent structural integrity resistant to hot cracking.
