Filler Metal, RG45, Display Pack: 1 lb; AWS Classification: R45; Material: Mild & Low Alloy Steel; Type: Braze and Solder OFW; Diameter: 3/32 In; Length: 36 In; Melting Point: 2800 DegF; Tensile Strength: 52500 psi – R45 is a general purpose, copper coated, oxyfuel gas welding rod used for welding most low carbon steels. It is a great selection when ductility and machinability are most important. You do not need a flux when brazing with this product, but puddling of the molten metal will bring any scale or impurities to the surface. While R45 & R60 seem like similar alloys, they were originally developed for oxyfuel welding, however they can be used for TIG welding in some applications. These alloys do not carry enough de-oxidizers typically needed with the GTAW process; therefore, it is not recommended.
