What is AWS Class ER312 MIG and TIG Filler Welding Wire?

The AWS Class ER312 MIG and TIG filler welding wire is a high-alloy austenitic stainless steel, boasting a composition of about 29% chromium and 9% nickel, which gives it remarkable resistance to cracking. It has a high tensile strength, typically around 110,000 psi, and maintains excellent toughness, even in low temperatures. This wire is designed for outstanding weldability on dissimilar metals and challenging steels. It creates strong, crack-resistant welds with minimal spatter, ensuring top-quality results. Plus, it keeps stable mechanical properties even under high-heat conditions, making it a dependable choice for structural and high-stress welding jobs.
