What is Stainless Steel ER308 Filler Wire?
Stainless ER308 filler wire is a welding wire made from austenitic stainless steel. It contains approximately 18% chromium and 10% nickel with small amounts of other elements such as molybdenum and manganese. This combination creates a corrosion-resistant material that can stand up to various environments.
The most common application for stainless steel ER308 filler wire is in MIG (Metal Inert Gas) welding processes. It is also commonly used in TIG (Tungsten Inert Gas) welding and MMA (Manual Metal Arc) welding processes due to its ability to weld materials together without leaving any spatter or residue behind. Furthermore, it can be used on carbon, low alloy steels, and non-ferrous metals such as Aluminium or copper alloys. For these reasons, it has become popular for many welders looking for reliable results across various materials and conditions.
Benefits of Stainless Steel ER308 Filler Wires
SS ER308 Filler Wires are an excellent choice for many welding projects because they offer some benefits. They are extremely durable and can be used in low- and high-temperature applications. They also have excellent oxidation and corrosion resistance due to their austenitic structure.
Stainless steel ER308 filler wires can be used for various welding applications, including MIG and TIG welding on austenitic stainless steels such as SS304/304L and SS316/316L. They are also suitable for joining dissimilar metals such as carbon and stainless steel and joining similar alloys such as 304L to 308L or 316L to 316Ti. They may also be used in oxyacetylene welding processes on certain grades of austenitic stainless steel.
Properties of Stainless Steel ER308 Filler Wires
Stainless steel ER308 filler wires have several properties that make them perfect for various welding tasks. The weld deposit has excellent fatigue strength due to its ferrite content which provides superior flexibility to other stainless steel filler wires. Additionally, these wires have good impact toughness at both room and cryogenic temperatures, making them suitable for use in cold climates or on components requiring frequent temperature fluctuations, such as cryogenic vessels or piping systems. Moreover, these wires produce minimal smoke when being welded, ensuring welders’ safety during the process.
