LINCOLN AROSTA 304L Stainless Steel Welding Electrode 4.0mm 4.4kg (83 pcs.)

The LINCOLN AROSTA 304L is a premium rutile-basic coated stainless steel electrode designed for welding austenitic stainless steels. This electrode offers excellent arc stability, low spatter, and a fine ripple appearance, making it ideal for high-quality welds in demanding applications. With a diameter of 4.0 mm and a package weight of 4.4 kg containing 83 pieces, it is suitable for both professional and industrial use.

Advantages

Excellent arc stability and low spatter ensure clean, efficient welding. Self-releasing slag reduces post-weld cleaning time. The electrode provides good corrosion resistance and high mechanical properties, including tensile strength >520 MPa and impact strength >47 J at -120°C. Suitable for all welding positions and compatible with AC and DC+ current.
