2215 duplex stainless steel electrodes meet the GB E2209-15 
 Rather AWS E2209-15 
 Description: 2215 is the base type drug skin ultra-low carbon duplex stainless steel electrode, deposited metal contains 40% -50% of ferrite, with excellent mechanical properties and corrosion resistance, particularly resistance to chloride is a reliable high resistance to corrosion and pitting corrosion. DC reverse, can be all-position welding. 
 Uses: Used for welding low carbon 00Cr22Ni5Mo3N, SAF2205 duplex stainless steel, etc..
