59796 - Avesta 316L-17 Stainless Stick Rod 4.0mm

Premium Avesta E316L AC/DC Stainless Steel Electrodes

The Avesta E316L AC/DC 4.0mm Stick Electrode is a high-performance consumable designed for the Shielded Metal Arc Welding (SMAW) of austenitic stainless steels. Engineered to meet the rigorous demands of industrial fabrication, this electrode conforms to AWS E316L-17 classification, offering a rutile-acid coating that ensures smooth operability. The core wire composition is strictly controlled to provide a weld metal that matches the corrosion resistance of Type 316 and 316L base materials. The inclusion of Molybdenum (Mo) in the alloy matrix significantly enhances resistance to pitting and crevice corrosion, particularly in environments containing chlorides or dilute acids.

One of the critical technical advantages of this Avesta electrode is its low carbon content (designated by the 'L'). By maintaining carbon levels below 0.04%, the electrode minimizes the risk of sensitization and intergranular corrosion (carbide precipitation) in the heat-affected zone, making it suitable for service temperatures up to 400°C. This makes the AVE59796 an essential choice for fabricating storage tanks, piping systems, and processing equipment in the chemical, petrochemical, and pulp and paper industries where aggressive media are present.

The 4.0mm diameter is specifically optimized for medium-to-heavy plate welding, allowing for higher deposition rates and efficient filling of joint preparations. The electrode is formulated to operate on both Alternating Current (AC) and Direct Current Electrode Positive (DCEP), providing versatility for workshops with varying power source capabilities. The slag system is designed to be self-releasing or easily detachable, leaving a finely rippled bead profile that requires minimal post-weld grinding or polishing. This balance of metallurgical integrity and operational efficiency makes the Avesta E316L a benchmark for quality in stainless steel maintenance and repair operations.
