An austenitic stainless welding wire suitable for joining similar metals such as AISI 304 and AISI 304L. Its low carbon content reduces the likelihood of chromium carbide precipitation at grain boundaries, thereby improving corrosion resistance. Apart from its higher silicon (Si) content, it is comparable in quality to 308L.
The increased Si content enhances arc stability and provides better fluidity and penetration in the weld pool, contributing to a smoother and more aesthetically uniform weld bead. However, if a low-ferrite or fully austenitic structure forms due to dilution from the base metal during welding, the weld metal may exhibit slightly higher susceptibility to cracking compared to lower-silicon grades.
