Product Catalog
Executive 308Si/308LSi is a stainless-steel welding wire for TIG and MIG. This wire is used to weld equipment made with 304 and 308 stainless grades. Welding speed is higher than 308 or 308L due to improved wettability of weld metal. The addition of silicon improves the usability of this alloy in the gas metal arc process producing a more fluid weld and cleaner bead then standard ER308L. If the dilution by the base metal produces a low ferrite or fully austenitic weld, the crack sensitivity of the weld is somewhat higher than that of a lower silicon content weld metal.
Application and Features
Typically used for 304/304L & 308/308L stainless steel grades this alloy is used in a variety of industries including chemical & food processing. Executive stainless-steel filler metal is characterized by its clean and consistent finishing which aids in welding.
This wire is also suitable for laser welding and WAAM applications (Wire Arc Additive Manufacturing, aka Metal 3D printing).
