Product Detail

Product Tags

Custom cast duplex stainless steel investment casting product from China casting foundry with machining, heat treatment, and surface treatment services.

RMC cast precision cast steel parts that consistently meet or exceed customer expectations. Lost wax investment casting allows us to produce metal parts as small as tens of grams and as large as tens of kilograms, in a wide range of ferrous and non-ferrous alloys and with exceptional dimensional accuracy.

The lost wax casting process produces near-net-shape precision metal parts that often require little or no additional machining. The resulting finish is also much better than what is achievable through other processes. The strength and durability of the casting parts make themselves ideal for high wear-resistance applications requiring millions of cycles.

precision Investment casting process

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.

Available grade of duplex stainless steel at RMC Casting Foundry: 1.4460, 1.4462, 1.4468, 1.4469, 1.4517, 1.4770, A 890 1C, A 890 1A, A 890 3A, A 890 4A, A 890 5A, A 995 1B, A 995 4A, A 995 5A, 2205, 2507, 022Cr22Ni5Mo3N, 022Cr25Ni6Mo2N

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.
