E308L-16 – 14″ x 1/8″ (4.4 LB) by SÜA
The E308L-16 electrode from SÜA is designed for all-position welding of low carbon chromium-nickel stainless steels like 304L and stabilized grades such as 321 and 347. Its low carbon content (0.04%) preserves corrosion resistance and minimizes intergranular degradation in the weld zone, making it suitable for x-ray quality welds. It offers easy arc strike and restrike, smooth arc action, low spatter, and a self-peeling slag, which helps clean up after welding.
Ideal uses include fabrication of stainless-steel components requiring consistent mechanical properties and corrosion resistance. The electrode supports both AC and DC polarity and performs well on welded joints that require high-quality, austenitic stainless steel deposits. Pay attention to packaging details and verify approximate electrode counts per pound in the product pictures before purchasing.

The electrode is designed for easy arc performance, low spatter, and a self-peeling slag.
Use this electrode for projects where lighter electrode packs are preferred or where multiple welds are needed with consistent results. As with similar products, verify the packaging and approximate counts per pound from the listing.
HARFINGTON E308L-16 Welding Rod – 1/16″ x 10″
The HARFINGTON E308L-16 welding rods are sized at 1/16 inch (1.6 mm) and 10 inches in length, with a typical 0.15 lb package. These rods are intended for stainless steel welding, compatible with both AC and DC power supplies and suitable for all-position welding. They are marketed for metal fabrication, maintenance, and repair work, offering reliable arc performance and corrosion resistance typical of E308L-16 alloys.
Consider these rods when working on smaller or detail-oriented stainless steel projects where precise control over heat input and filler metal is important. They’re handy in workshops that routinely perform stainless steel repairs and fabrications on household or industrial equipment.
E309L-16 3/32″ x 12″ Stainless Steel Electrode (8 oz to 5 lb options)
The Hy-weld E309L-16 electrode is designed for all-position welding of a broad range of stainless steels, including heat-resistant 22-25% chromium and 12-13% nickel grades. It supports welding to itself and to other austenitic grades, as well as to martensitic and ferritic stainless steels, enabling versatile welds across different alloys. The 0.04% carbon content helps maintain favorable ferrite content and corrosion resistance in the weld.
Ideal for projects where dissimilar stainless steel joints are necessary, or where a single electrode type must cover multiple stainless steel grades. The electrode’s wide compatibility makes it a practical choice for repair work, industrial fabrication, and equipment maintenance where corrosion resistance is essential.
SÜA – E309L-16 – 14″ x 1/8″ (4.4 LB)
The E309L-16 electrode from SÜA is intended for all-position welding of high-chromium and nickel-containing stainless steels, including 309/309L types. It supports welding to a range of stainless grades such as 304L, 308L, 310, 316L, 321 or 347, and even to martensitic and ferritic stainless grades. Its low carbon content helps preserve intergranular corrosion resistance and yields a higher ferrite content than standard 309-16 deposits. This makes it suitable for joints requiring robust corrosion resistance and structural integrity across dissimilar stainless steels.
Consider this electrode when you need to weld multiple stainless steel grades in a single project or when repairing complex stainless assemblies that demand reliable corrosion resistance in the weld metal.

Buying Guide: Key Purchase Considerations
- All-position welding capability: Many stainless steel electrodes, like E308L-16 and E309L-16, are designed for all-position use; ensure the electrode type matches your typical welding orientations (flat, horizontal, vertical, overhead).
- Carbon content and corrosion resistance: Electrodes labeled with low carbon content (for example, 0.04% C) help minimize intergranular corrosion and maintain the weld’s corrosion resistance in steel like 304L and 308L.
- Grade compatibility: E308L-16 is well-suited for joining 304L, 321, 347, and similar austenitic grades. For dissimilar joints (e.g., 304 with 316), consider 309L or 309L-16 variants depending on weld requirements.
- Diameter and length: Choose electrode size based on welding current, position, and joint design. Thicker electrodes (like 3/32″ or 1/8″) require higher current; thinner variants enable finer control for fillet welds or tight gaps.
- Spatter and slag: Electrodes with low spatter and self-peeling slag simplify cleanup and improve productivity, especially in production environments.
- Package weight and counts: Electrodes are sold in various weights (e.g., 2 lb, 4.4 lb, 5 lb). For frequent use, higher-weight spools reduce reordering frequency; for occasional projects, lighter packs reduce storage burden.
- Voltage and polarity compatibility: Most E308L-16 and E309L-16 rods are compatible with common AC or DC welding machines. Check your machine’s polarity settings to maximize arc stability and deposit quality.
- Grain structure and imaging: Some electrodes advise checking pictures for approximate counts per pound. If you’re tracking inventory for a shop, this helps with planning and cost accounting.
- End-use considerations: For critical components in food-grade or medical environments, verify that the electrode chemistry supports the required corrosion resistance and post-weld cleaning attributes.
Comparative Considerations
- Choosing E308L-16 vs. E309L-16: If you need uniform corrosion resistance in 304L or 308L systems with minimal ferrite variation, E308L-16 is a strong default. For dissimilar stainless steel joints or higher chromium contents, E309L-16 may provide better performance.
- Manufacturer differences: While many electrodes share core attributes (low carbon content, all-position suitability), performance can vary slightly in arc characteristics and slag behavior. It’s often useful to test a few brands in your specific shop environment.
- Package and handling: Some packages include explicit guidance about electrode counts per pound or quantity estimates. For large shops, standardizing on a single packaging type can simplify inventory control.
Across these products, the common thread is reliable stainless steel performance, with emphasis on low carbon content and all-position capability. When selecting electrodes, align the choice with your base metal grades, joint design, and welding method to optimize weld integrity and corrosion resistance.
