316LSi Tig

type 
Austenitic Tig rod with excelent resistance against general corrosion.
applications 
The alloy is widely used in the chemical and food-processing industries, as well as in shipbuilding and various types of architectural structure.
Properties 

316LSi offers good general corrosion resistance, particularly to corrosion in acid and chlorinated environments. The alloy has a low carbon content which makes it particularly recommended when there is a risk of intergranular corrosion. The higher silicon content improves the welding properties such as wetting and results in a bright seam.
