Dissimilar metal welding made easy – strength, stability, and corrosion resistance

Superon Super Optimal 309L-17 MMA Electrodes are rutile-basic coated stainless steel electrodes designed for welding dissimilar steels and joining stainless to mild or low-alloy steels. With a low carbon content (L-grade), these electrodes provide excellent resistance to intergranular corrosion and ensure crack-free welds, even on difficult joints.

Engineered for high integrity and easy handling, Super Optimal 309L-17 offers a stable arc, minimal spatter, and smooth bead appearance in all welding positions.

Key Features

  • Low Carbon 309L Stainless Alloy – Ideal for dissimilar joints and transition layers
  • Excellent Corrosion Resistance – Resists intergranular attack and heat-induced corrosion
  • Rutile-Basic Coating – Smooth arc, low spatter, and easy slag removal
  • Crack-Resistant Welds – Designed for high-stress and difficult-to-weld materials
  • All-Position Use – Reliable performance for on-site or workshop welding.

Typical Applications

  • Joining stainless to mild or carbon steels
  • Buffer layers before cladding
  • Welding high-alloy stainless steels to carbon steel
  • Maintenance and repair of chemical plant and food industry equipment
  • Structural steelwork requiring high corrosion resistance

Suitable Base Materials

  • Stainless steel grades (304, 309, 316)
  • Carbon steel and low-alloy steels
  • Dissimilar metal combinations (e.g., 304L to mild steel)
