JACKSUN NOVA 308L

SPECIFICATIONS - AWS A5.4 E308L-16

JACKSUN NOVA 308L is a rutile-coated stainless steel electrode conforming to AWS A5.4 E308L-16, designed for welding low-carbon 18Cr-8Ni stainless steels (AISI 304L, 308L, and equivalents). The reduced carbon content (≤0.04%) minimizes carbide precipitation and enhances intergranular corrosion resistance, making it ideal for chemical, food processing, and cryogenic applications.
