OVERVIEW

Premium E309L-17 Stainless Steel Electrode for Dissimilar Joints

The ESAB OK 67.60 is a high-performance, acid-rutile coated stick electrode classified as E309L-17. Engineered for the most demanding industrial applications, this consumable is the industry standard for joining stainless steels (AISI 309 type) to mild or low-alloy carbon steels. Its over-alloyed composition (approximately 24% Cr, 13% Ni) is specifically calculated to handle the dilution from carbon steel base metals while maintaining a high-quality, crack-resistant austenitic stainless steel weld deposit.

One of the critical technical advantages of the OK 67.60 is its low carbon content (indicated by the 'L' designation), which significantly reduces the risk of carbide precipitation and subsequent intergranular corrosion. This makes it an excellent choice for applications where corrosion resistance is paramount. Furthermore, the electrode produces a weld metal with a substantial ferrite number, providing robust resistance to hot cracking—a common challenge when welding dissimilar heavy sections.

The '17' coating designation implies a silica-titania based flux that supports both AC and DC+ polarity. This coating formulation delivers a smooth, spray-type transfer with very low spatter levels and a flat to slightly concave bead profile. The slag system is designed to be self-detaching in many cases, reducing post-weld cleaning time and improving overall productivity. It is also widely used for depositing buffer layers on carbon steel before overlaying with 308L or 316L filler metals.

FAQ

E309L-17 electrodes are primarily used for welding dissimilar metals, such as joining stainless steel to mild steel, and for applying buffer layers on carbon steel.

Yes, the OK 67.60 is designed to operate smoothly on both AC (Alternating Current) and DC+ (Direct Current Electrode Positive).

The 'L' stands for 'Low Carbon'. This indicates a maximum carbon content of 0.04%, which helps prevent intergranular corrosion and carbide precipitation.

No, E309L-17 electrodes with rutile coatings are generally suitable for flat, horizontal, vertical-up, and overhead positions, but not vertical-down.

If the electrodes have been stored properly (e.g., in ESAB VacPac or hermetically sealed containers), baking is usually not required. If exposed to moisture, redrying at 350°C for 2 hours is recommended.

For a 2.5mm E309L-17 electrode, the recommended amperage range is typically between 50A and 90A, depending on the position and base material thickness.

309L has a higher alloy content (Chromium and Nickel) than 308L. This allows it to tolerate dilution from the mild steel side of the joint without becoming martensitic or cracking.

Yes, it is excellent for the first layer of cladding on carbon steel (the buffer layer). Subsequent layers can be done with 308L or 316L.
