DETAILS

B9 (P91) alloyed steel designed to weld equivalent 'type 91' steels for improved long term creep resistance

Features

  • B9 (P91) alloyed steel: Modified 9CrMo designed to weld equivalent "type 91" 9CrMo steels modified with small additions of niobium, vanadium and nitrogen for improved long term creep resistance
  • 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

  • Oil Refineries
  • Coal Liquefaction and Gasification Plants
  • Main Steam Piping
  • Valves and Turbine Casings
  • Power Generation Plants

Welding Positions

  • All, except vertical down
