CHROMET® 9-B9

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

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>

Typical Applications

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

Welding Positions

• All, except vertical down
