317 electrodes have a greater molybdenum content than USA 316. The increased molybdenum content results in a weld deposit with higher tensile strength at elevated temperatures, stronger resistance against pitting corrosion, and virtually immune from cracking as the deposit cools down from the molten stage. USA 317 weld deposits exhibit smooth bead appearance and easy slag removability. This electrode is typically used where strong corrosion resistance against sulfuric or sulfurous acids is required such as in the chemical, paper and textile industries.
