BLUME® E8015-B2 Datasheet

Q: What metals can BLUME® E8015-B2 weld?
A: It’s specially designed for 1.25% Cr – 0.5% Mo steels, commonly used in boilers, pressure vessels, and high-temperature piping systems.

Q: What’s the difference between E8015-B2 and E8018-B2?
A: E8015-B2 has a sodium-based coating for deep penetration and DC+ polarity, ideal for root passes, while E8018-B2 has a potassium-based coating for smoother arc starts and easier slag removal.

Q: Does it require rebaking before use?
A: Yes. For optimal low-hydrogen performance, rebake at 650°F (340°C) for one hour before welding.

Q: Is it suitable for all welding positions?
A: Yes, BLUME® E8015-B2 performs reliably in flat, vertical, horizontal, and overhead positions.
