BLUME® E9015-B9 Datasheet

Q: What base metals can BLUME® E9015-B9 weld?
A: It’s specially designed for 9Cr-1Mo steels (Grade 91) used in high-temperature, high-pressure service such as boilers, reactors, and piping systems.

Q: Can BLUME® E9015-B9 be used for field and shop fabrication?
A: Yes, it’s ideal for both. Its smooth arc stability and low hydrogen levels ensure dependable welds in all controlled environments.

Q: How does it compare to E9015-B3?
A: E9015-B9 offers superior creep and oxidation resistance for higher service temperatures, whereas E9015-B3 is suited for moderate-temperature applications.

Q: Is preheat or post-weld heat treatment required?
A: Yes — preheating and post-weld heat treatment (PWHT) are recommended to ensure optimal mechanical properties and reduce cracking risk.

Q: What storage conditions are required?
A: Keep electrodes dry and moisture-free. If moisture exposure occurs, rebake at 650°F (340°C) for 1 hour before use.
