DETAILS
Low Alloy, Low Hydrogen • AWS A5.5M E9015-B92 H4
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
- 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 except vertical down
