DETAILS
Basic coated stick electrode made on matching core wire. Moisture resistant coatings giving very low weld metal hydrogen levels.
Features
- B9 (P92) alloyed steel: 9Cr steel designed to weld equivalent 'type 92' steels modified with tungsten, vanadium, niobium, nitrogen, and a small addition of boron to give improved long term creep properties
- Excellent tensile strength in creep regime
- Moisture resistant coating provides low amounts of weld metal hydrogen levels for a superior weld
- Specifically designed for high integrity structural service at elevated temperature
Typical Applications
- Headers
- Main steam piping
- Turbine castings
- Power generating plants
Welding Positions
- All position, except vertical down
