The E309L-17 electrodes are premium stainless-steel coated MMA rods designed to weld Cr–Ni austenitic stainless steels and to safely join stainless to mild or low-alloy steels. Their over-alloyed weld metal and controlled ferrite content deliver a tough, corrosion-resistant deposit suitable for demanding applications such as structural stainless, clad joints, repair work, and chemical or food-grade fabrications.
These electrodes perform reliably under AC or DC+, with stable arc behaviour, smooth slag detachability, minimal spatter and consistent weld quality — making them a workshop staple for professional welders working with stainless or mixed-metal jobs.
Key Features
Standard-Classified E309L-17 Stainless Electrodes — Conforms to AWS A5.4 / EN ISO 3581-A standards; suitable for CrNi stainless steels and clad/bimetal combinations.
All-Position & AC/DC-Capable — Works under AC or DC+ currents, and can be used in multiple welding positions (flat, horizontal, vertical, overhead) depending on electrode diameter.
Excellent Corrosion & Heat Resistance — The weld deposit’s composition (high Cr/Ni and controlled ferrite) gives good resistance to general corrosion, intergranular attack and maintains integrity at elevated temperatures — making it suitable for stainless steel fabrication and repair.
Smooth Arc & Clean Weld Finish — The acid-rutile coating promotes a stable, easy-striking arc, minimal spatter, and smooth slag removal — ideal for clean weld beads and reduced post-weld clean-up.
Reliable Mechanical Properties — Typical weld metal exhibits high tensile strength (~580 MPa), good elongation and good toughness, giving structural integrity and durability.
Large 5 kg Pack — Good for Workshop & Batch Work — High volume packaging makes this ideal for heavy-use, production, or repeated stainless projects without frequent reordering.
