Product Description
E9015-B3 Heat-Resistant Stainless Steel Welding Electrode

According to GB E6015-B3
Corresponding with AWS E9015-B3

 
Introduction: 
E9015-B3 is a kind of Cr2.5%-Mo1% 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 Cr2.5Mo pearlitic heat-resistant steel structures, such as high temperature high pressure pipes below 550ºC, chemical equipment for synthesis, equipment for petroleum cracking.
