Special Design for Precision Machining - Super Duplex Stainless Steel Investment Casting Impeller – RMC Foundry Detail:
Duplex stainless steel casting means the castings made of duplex stainless steel. Duplex Stainless Steel (DSS) refers to stainless steel with ferrite and austenite each accounting for about 50%. Generally, the content of less phases needs to be at least 30%. In the case of low C content, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some duplex stainless steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.
The DSS has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and ductility, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining brittleness, high thermal conductivity, and superplasticity as ferrite stainless steel. Compared with austenitic stainless steel, DSS has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
In casting production, most of the stainless steel castings are completed by investment casting. The surface of stainless steel castings produced by investment casting is smoother and the dimensional accuracy is easier to control. Of course, the cost of investment casting stainless steel parts is relatively high compared to other processes and materials.
