JQ.S2215

According with GB E2209-15
Corresponding with AWS E2209-15

Introduction: JQ.S2215 is a kind of ultra-low-carbon dual-phase stainless steel electrode with basic coating. The deposited metal contains 40%-50% ferrite. It has excellent mechanical properties and corrosion-resistance, especially reliable chloride corrosion-resistance and high pitting corrosion-resistance. It has excellent welding performance. DCRP (Direct Current Reversed Polarity). All-position welding.

Uses: Used for welding ultra-low-carbon dual-phase stainless steel like 00Cr22Ni5Mo3N, SAF2205, etc.
