Duplex Stainless Steel Additive Manufacturing

Print Complex Metallurgy Consistently with ADDere

While Duplex Stainless has a variety of up-sides, including corrosion resistance, heat transfer and even greater strength to weight than other grades of stainless steel, it also presents certain metallurgical considerations that could make it difficult to work.  These characteristics that makes Duplex Stainless Steel attractive to the petrochemical, oil & gas, solar and nuclear power industries, also require machining and fabrication processes to be extraordinarily careful.


With the ADDere laser-wire additive manufacturing process, with its precision laser heating and closed-loop control system, allows for precise heat control across the entire 3D metal print build. This keeps the Duplex Stainless Steel microstructure consistent across the entire additive metal build. 


Going with Additive manufacturing in duplex stainless steel also reduces the machining requirements on complex components, reducing cost as well as the issues revolving around the complexities of welding the material.
