308LSi filler metal is also suitable for welding titanium and niobium stabilised steels such as 321 and 347 in cases where the construction will be operating at temperatures not exceeding 400°C.
308LSi has enhanced silicon content which improves the fluidity of the melt pool with a minimum of spatter and porosity, this also ensures a nice and smooth weld surface.
