ER316LSi SS MIG WIRE | FEATURES
- ER316LSi is the same as ER316L, except for the higher silicon content.
- It improves the usability of the filler metal in the gas metal arc welding process.
- If the dilution by the base metal produces a low ferrite or fully austenitic weld, the crack sensitivity is somewhat higher than that of a lower silicon content weld metal.
- Welding process of ER316LSi SS MIG wire applied to MIG(Metal Inert Gas Welding) or GMAW(Gas Metal Arc Welding).
