Description:

DuraMax E9015-B9 is a 9.0% Cr – 1.0%Mo, low hydrogen electrode modified with niobium and vanadium. It is designed to provide improved creep strength, toughness, fatigue life, and oxidation and corrosion resistance at elevated temperatures.

Typical Application & Usage:
  • For joining applications on higher chromium 9CrMoNb steel .
  • Intended for high integrity structural service at elevated temperatures.
  • DM9015-B9 offers improved toughness and better creep properties, which ultimately
    allow for higher steam temperatures and the use of thinner wall piping.
  • Power plants, steam boilers.
 RE-DRY CONDITIONS: Re-Dry the electrode at 250°C for 1 hour before use.
