Low Alloy, Low Hydrogen • AWS A5.5 E9015-B91 H4

Características

  • 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)
