Autocraft 309LSi is a premium quality, low carbon 24% Cr / 13% Ni stainless steel wire for the Gas Metal Arc Welding (GMAW) of matching 309L type stainless steel. Autocraft 309LSi is also suitable for a wide range of other welding applications including; F The dissimilar joining of “300 series” and selected “400 series” stainless steel grades to mild or low alloy steels, An intermediate or buttering layer in the butt welding of clad steels, A stainless steel overlay on mild or low alloy steel, A ‘buttering’ layer prior to hardfacing. The low carbon content ensures immunity from carbide precipitation and intergranular corrosion when welding low carbon stainless steel grades and the higher Silicon level offers improved arc stability, bead shape and edge wetting.
