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
Weld metal chemistry is low in impurity elements allowing it to respect the X Factor (<15ppm) and J-factor (<120ppm)
