E2209-15
Description:
E2209-15 is an alkali-based ultra-low carbon duplex stainless steel electrode with 40% -50% ferrite in the deposited metal. It has excellent mechanical properties and corrosion resistance. In particular, it has reliable resistance to chloride Corrosion performance and high pitting corrosion resistance. DC reverse connection, all-position welding.
use:
For welding ultra-low carbon 022Cr22Ni5Mo3N, SAF2205 duplex stainless steel.
