High Quality Steel Investment Casting - Custom Valve Housing of Cast Duplex Stainless Steel – RMC Foundry Detail:
Custom valve housing of duplex stainless steel produced by investment casting 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 stainless steel casting products 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 investment casting process produces near-net-shape precision castings that often require little or no additional machining. The resulting finish is also much better than what is achievable through other casting or manufacturing processes. The strength and durability of the casting parts make themselves ideal for high wear-resistance applications requiring millions of cycles.
The Steps of Investment Casting Process:
During the investment casting process, a wax pattern is coated with a ceramic material, which, when hardened, adopts the internal geometry of the desired casting. In most cases, multiple parts are cast together for high efficiency by attaching individual wax patterns to a central wax stick called a sprue. The wax is melted out of the pattern – which is why it is also known as the lost wax process – and molten metal is poured into the cavity. When the metal solidifies, the ceramic mold is shaken off, leaving the near net shape of the desired casting, followed by finishing, testing and packaging.
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.
