Stainless Steel Welding Electrode
AF2209-15
GB/T E2209-15
AWS A5.4 E2209-15
Description: AF2209-15 is an ultra-low carbon nitrogen-containing duplex stainless steel electrode with low hydrogen coating. Use DCEP (direct current electrode positive). The operating performance is great. Because it contains molybdenum and nitrogen, and the carbon content is extremely low, the deposited metal has good crack resistance and corrosion resistance, especially stress corrosion resistance.
Application: It is mainly used for welding the same type of ultra-low carbon stainless steel materials in petroleum and hydraulic industries. Such as the welding of 022Cr22Ni5Mo3N duplex stainless steel.

Notice:
1. The electrode must be baked for 1 hour at around 250℃ before welding operation;
2. It is essential to clean up rusty, oil scale, water, and impurities on welding parts before welding.
