Features and Applications
- Used in welding of heat resistant T/P92 and Cr-Mo alloyed similar steels used in power generation plants and steam pipes.
- Provides creep strength and toughness at elevated temperatures with additional alloying elements
- Weld metal is resistant to temperatures up to +650°C
- Bruscato factor of X<15
- Preheat and interpass temperature should be used at 200-315 °C.
- The test assembly shall then be allowed to cool in the furnace, at a rate not greater than 200°C per hour, and may be removed from the furnace when the temperature of the furnace has reached 300°C and allowed to cool in still air
- Re-drying: 300-350°C / min. 2h
Current Type
- DC(+)
