E8015-B2

According with GB E5515-B2
Corresponding with AWS E8015-B2

Introduction: E8015-B2 is a kind of Cr1%-Mo0.5% pearlitic heat-resistant steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. The weld should be given preheating and post-weld heat treatment according to their structural features.

Applications: Used for welding Cr1%-Mo0.5% heat-resistant steel below 520℃, such as boiler pipes, high pressure vessels, equipment for petroleum refining, etc. Also used for welding 30CrMoSi cast steel.
