CHARACTERISTICS & APPLICATIONS

íshín-316B has nominal composition (wt. %) of weld metal 18.5 Cr, 12.5 Ni, 2.5 Mo. These electrodes are used for welding Type 316 and similar alloys. They have been used successfully in certain applications involving special base metals for high-temperature service. For these high-temperature applications in the past, the carbon level would have been about 0.06%. For similar current or future applications, the use of E316H would ensure similar carbon levels. The presence of molybdenum provides creep resistance and increased ductility at elevated temperatures.

These electrodes are usable with dcep (electrode positive) only. While use with alternating current is sometimes accomplished, they are not intended for use with this type of current. Electrode sizes 4.0 mm and smaller may be used in all positions of welding.

Storage and Drying Conditions: Hydrogen can have adverse effects on welds in some steels under certain conditions. One source of this hydrogen is moisture in the electrode coverings. For this reason, the proper storage, treatment, and handling of electrodes are necessary.

Holding Ovens: 125°C–150°C.

Drying Conditions: 250°C–425°C for 1 hour prior to use.
