Features and Applications
- Used for the welding of high heat resisting. Cr-Mo alloyed steels which are used for the production of boilers tubes and pipes and nitrided steels
- Weld metal is resistant to temperatures up to +570°C
- Shielding gases: MAG; Ar+CO2 and Ar+O2 mix gases, TIG; pure Ar gas can be used
- Preheat and interpass temperature should be used at 150-250 °C
- The test assembly shall be cooled in the furnace to 300 °C at a rate not exceeding 200 °C/h.
