Features and Applications
- These electrodes are used primarily for welding stainless steel, such as Types 16-8-2, 316, and 347, for high-pressure, high-temperature piping systems.
- The weld deposit usually has a Ferrite Number no higher than 5 FN.
- The deposit also has good, hot ductility properties which offer relative freedom from weld or crater cracking even under high-restraint conditions.
- The weld metal is usable in either the as-welded or solution-treated condition.
- These electrodes depend on a very carefully balanced chemical composition to develop their fullest properties.
- Corrosion tests indicate that Type 16-8-2 weld metal may have less corrosion resistance than Type 316 base metal depending on the corrosive media.
- Where the weldment is exposed to severely corrosive agents, the surface layers should be deposited with a more corrosion-resistant weld metal.
- Basic coated electrode is used primarily for welding stainless steel, such as types 16-8-2, 316, and 347, for high pressure, high-temperature piping systems
- A controlled chemical composition and ferrite number (<5 FN) of weld metal gives good creep, oxidation and general corrosion resistance
