Select 309LSi is a bare stainless steel wire electrode for gas-metal arc welding. This electrode has a nominal composition of 24% Cr, 13% Ni and 0.8% Si, with a maximum carbon content of 0.03%. The higher silicon level improves bead wetting. The low carbon in this alloy minimizes carbide precipitation and makes it more resistant to intergranular corrosion. The increased silicon improves the usability of the electrode during the welding process.
Applications
Select 309LSi is well suited to weld base metals of similar composition and may be used to join carbon and low alloy steels to austenitic stainless steels.
Typical applications include the welding of refinery and chemical processing equipment, furnace parts, and auto exhaust parts.
Caution
Protect yourself and others read the safety data sheet prior to using this product.
