DETAILS
These consumables are designed to weld equivalent ‘grade 92’ 9Cr-Mo steels modified with tungsten, vanadium, niobium, nitrogen and a small addition boron to give improved long term creep properties.
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
- P92 steel has rupture strength up to 30% greater than that of P91 steel
- Specifically designed for high integrity structural service at elevated temperature

- Main Steam Piping
- Oil Refineries
- Coal Liquefaction and Gasification Plants
- Power Generation Plants
- Turbine Castings
Welding Positions
- All
