Hilchrome 308R welding electrodes E308L-17 - E 19 9 LR 32
Hilchrome 308R is a rutile coated electrode for welding low carbon 18Cr10Ni austenitic stainless steel grades like AISI 304, 304L. Typical applications include all industries where similar materials (incl. higher carbon types) as well as ferritic 13% Cr steels are used. Hilchrome 308R is also suitable for Nb (Cb) or Ti stabilised grades 347 and 321. Weld metal has an excellent resistance to general and intergranular corrosion (up to 350°C), good resistance to oxidising acids and cold reducing acids. Hilchrome 308R is a core wire alloyed all-current type (AC/DC).
