The ER312 stands out due to its unique composition. It is an austenitic stainless steel wire containing a significant amount of chromium and nickel, which gives it excellent resistance to corrosion. Mechanically, it is known for its high strength and impressive ductility, creating welds that are both tough and crack-resistant. This combination allows it to produce smooth, stable arcs with minimal spatter, whether you are using the MIG or TIG process, leading to clean, high-quality weld deposits every time.
