Esab Arcaloy 308L-17 Plus description: Arcaloy 308L-17 Plus electrodes have a heavy coating, produce a concave bead with minimum ripple and the slag is virtually self-cleaning. These electrodes are designed to weld Types 304, 304L, 321 and 347 for corrosion service at temperature up to about 600F(315C).The excellent wetting action and very fine ripple minimize crevice corrosion and grinding time. This is particularly useful in the food and drink industry where a smooth polished surface is required.
