Duplex stainless steel alloys are excellent for a variety of specialized investment casting applications. These alloys are composed of ferritic (magnetic) and austenitic (nonmagnetic) stainless steels to achieve the desired characteristics that result from combining the component alloys. By adjusting the proportions and utilizing other additives, duplex alloys can be fine-tuned to increase strength, to resist corrosion, to weld better, to perform well at cold temperatures and more. Consulting with an experienced metallurgist is highly recommended.
