6760403020 - ESAB OK 67.60 4.0mm Stainless to Mild Steel Stick Electrode

High-Performance Dissimilar Welding Electrode

The ESAB OK 67.60 is a premium acid-rutile coated stick electrode classified as E309L-17, specifically engineered for the welding of stainless steels to mild and low-alloyed steels. With a diameter of 4.0mm, this electrode is optimized for applications requiring higher deposition rates while maintaining excellent bead aesthetics and metallurgical integrity. It is the ideal choice for depositing transition layers when surfacing mild steel with stainless steel weld metal, ensuring a robust bond and preventing carbon migration issues common in cladding operations.

One of the standout characteristics of the OK 67.60 is its user-friendly arc behavior. The acid-rutile coating provides a very stable arc with minimal spatter, making it accessible for welders of varying skill levels. It operates effectively on both AC and DC+ currents, offering flexibility in power source selection. The slag system is designed to be self-releasing, leaving a smooth, clean weld bead that requires minimal post-weld grinding or brushing. This feature is particularly beneficial in production environments where cleanup time impacts overall efficiency.

Metallurgically, the E309L-17 composition offers a high ferrite content, which provides excellent resistance to hot cracking—a critical factor when welding dissimilar metals where dilution can create unpredictable alloy compositions. The low carbon content (indicated by the 'L') further minimizes the risk of intergranular corrosion. Whether used for industrial fabrication, heavy equipment repair, or specialized maintenance, the ESAB OK 67.60 delivers consistent, high-quality results.
