JACKSUN NOVA 309

SPECIFICATIONS - AWS A5.4 E309-16

JACKSUN NOVA 309 is a rutile-coated stainless steel electrode conforming to AWS A5.4 E309-16. It is specially developed for welding dissimilar steels such as carbon steel to stainless steel, low alloy steels to stainless steel, and also for buffer layers and overlays. The higher chromium and nickel content provides excellent resistance to cracking and oxidation.
