What is Stainless Steel ER308 Filler Wires?

Iron makes up the majority of stainless steel ER308 filler wires, with 18–21% chromium and 9–11% nickel, as well as trace amounts of silicon, carbon, and manganese. This composition offers exceptional protection against oxidation and corrosion, especially for austenitic stainless steels such as 304 and 304L. Mechanically, ER308 provides good ductility with elongation usually above 30%, a tensile strength of about 570 MPa, and a yield strength of about 350 MPa. It guarantees uniform mechanical qualities, low levels of spatter, and a smooth bead appearance in a variety of welding positions and shielding gas combinations.

Stainless Steel ER308 Filler Wires Uses

MIG and TIG welding applications involving 304, 304L, and other comparable austenitic stainless steels frequently use stainless steel ER308 filler wires. They are frequently used in the construction and maintenance of pharmaceutical machinery, brewery tanks, chemical processing units, and food processing equipment. These wires are ideal for welding storage tanks, kitchenware, and architectural structures because they offer exceptional corrosion resistance in mildly corrosive environments. Additionally, ER308 is perfect for pressure vessels and piping systems that are subjected to low temperatures and non-aggressive chemical environments. It is a standard option for premium stainless welding due to its reliable arc performance and smooth finish.

Industry We Serve
