AWS 5.9 ER308LSi Welding Rod

AWS A5.9 ER308LSi for 304L welding

Welder metals is one of the leading manufacturers, suppliers, exporters, stockiest of SS MIG/TIG welding consumables such as wires, rods and electrodes.

AWS A5.9 /ASME SFA 5.9 is the specification for welding consumables: wires, electrodes and rods for arc welding of stainless and heat-resisting steels. ER308LSi is the low carbon, high silicon, high tensile type of 308 stainless steel MIG wire and rods. The ultra-low carbon and increased silicon content assures better arc stability and excellent bead appearance with less porosity and spatter. It has excellent resistance to intergranular corrosion and cracks sensitivity, mainly used for welding 18Cr-8Ni stainless steel or where matching filler metals are required for 304L materials, also used for overlay welding as well as certain dissimilar welds of carbon steel to stainless steel in railway rolling stock pressure vessel, chemical machinery, muffler welding.
