INOX R 25/14/3 NC
Description and application:
Austenitic-ferritic rutile, low carbon electrode for welding corrosion and heat resistant stainless steels and steel
castings up to 1150°C. Suitable for joining dissimilar steels.
Base materials:
- High-strength, unalloyed and alloyed constructional steels and heat treatable steels among themselves or among
each other.
- Unalloyed and alloyed boiler steels or constructional steels with highly alloyed chromium, CrNi and CrNiMo steels.
- Combination between ferritic and austenitic steels for steam boiler and pressure vessel constructions.
- Weld claddings: for the first layer of corrosion resistant weld claddings on HI, HII,StE 255, 17Mn4, StE 355-StE500
- For the first layer of corrosion resistant weld claddings on high.temperature, heat treated, fine-grained
constructional steels.
