What is Stainless Steel ER 310 Welding Wire?

The Stainless Steel ER 310 Welding Wire consists of about 25% chromium and 20% nickel, creating a fully austenitic structure that boasts impressive high-temperature strength and oxidation resistance. It typically offers a tensile strength of around 570 MPa, along with good ductility and toughness under thermal stress. This filler metal can withstand scaling up to 1100°C (2010°F), making it perfect for high-temperature applications. Designed for both MIG and TIG welding processes, ER 310 provides a stable arc, excellent bead control, and dependable metallurgical performance when welding 310 and similar heat-resistant stainless steels.
