Product Catalog
Executive 307Si is an austenitic stainless steel wire with extremely low ferrite. This alloy is basically a modified 307 with higher manganese to improve hot cracking resistance. The high silicon content provides very good wettability, which ensures a smooth spatter free weld deposit.
Application and Features
This alloy is a good choice for welding thick plates such as armor plate, manganese steel and wear plates. It is also a very good choice for welding of dissimilar metals like carbon steel to stainless steel, where a PWHT is required. The resulting weld deposit possesses corrosion resistance up to 1,500°F. Executive 307Si is also a good option as a buttering first pass layer for many hard facing alloys.
This wire is also suitable for laser welding and WAAM applications (Wire Arc Additive Manufacturing, aka Metal 3D printing).
