Among the specialized investment casting alloys is duplex stainless steel. These alloys are are composed of ferritic (magnetic) and austenitic (non-magnetic) stainless steels to deliver specific characteristics required for diverse applications. The foundry adjusts the proportions and adds other components to fine-tune the alloy. This achieves increased strength, corrosion resistance, welding performance, cold temperatures tolerance and more. An experienced metallurgist can deliver duplex stainless steel castings that are excellent for many specialized applications.
