Mitchell Stainless is based in Hamilton, New Zealand, and provides AWS Class ER347 SAW and Flux for the industry that demands the welding of stabilized stainless steel. This particular welding material is designed for operations that have been working at elevated temperatures. Mitchell Stainless’ ER347 SAW and Flux is the company’s offering for the welding industry that aims for excellence and requires the best welding materials. It was specifically designed for the creation of strong and crack-resistant welds that would have a long life.
ER347 SAW wire is niobium-stabilized austenitic stainless steel alloy resistant to chromium carbide precipitation when subjected to high temperatures. This is highly beneficial for improving resistance to intergranular corrosion. The alloy is further complemented with high tensile strength and resistance to creep when the weld metal is joined with an appropriate flux. The careful composition of this alloy is ideal for improving weldability while providing hot crack resistance. The weld metal is also resistant to high temperatures.
