Hilchrome 309R welding electrodes Ø 2,5 x 300mm - E309L-17 - E 23 12 LR 32
Hilchrome 309R is a rutile coated electrode for welding corrosion resistant and heat resistant CrNi steels, joining dissimilar metals and buffering. Typical applications include joining high-strength steels, un- and low alloyed heat treatable steels, stainless, ferritic chromium and austenitic chrome-nickel steels, austenitic manganese steels. The electrode suitable for joining clad steels. The FN content (FN ~17) ensures good cracking resistance. Hilchrome 309R is a core wire alloyed all-current type (AC/DC).
