The electrode can withstand attack by water in various physical forms. It is also resistant to corrosion by phosphoric, sulfuric, and mild organic acids. It is suitable for environments of high pressure, velocity, and temperatures. The alloy has excellent weldability, and it is not prone to biofouling. The filler metal can withstand conditions in seawater and thus ideal for such applications. The quality of the alloy is enhanced through cold working only because it is not responsive to heat treatment. Manganese is used to improve resistance to oxidation and sulfurization. Iron is also found in the alloy, and it acts as an agent that enhances the ability of the filler metal to resist erosion.
