The most widely-used materials of stainless steel mainly include (but not limited to): Stainless Steel: AISI 304, AISI 304L, AISI 316, AISI 316L, 1.4404, 1.4301 and other stainless steel grade.
Stainless steel has a minimum chromium content of 10.5%, making it more resistant to corrosive liquid environments and to oxidation. It is highly corrosion resistant and wear resistant, provides excellent machinability, and is well-known for its aesthetic appearance. Stainless steel investment castings are "corrosion-resistant" when used in liquid environments and vapors below 1200°F (650°C) and "heat-resistant" when used above this temperature.
The base alloy elements of any nickel-base or stainless steel investment casting are chromium, nickel, and molybdenum (or "moly"). These three components will determine the casting's grain structure and mechanical properties and will be instrumental in the casting's ability to combat heat, wear, and corrosion.
Our foundry can manufacture custom stainless steel investment castings that match your exact design specifications. For parts ranging from tens of grams to tens of kilograms or more, we provide tight tolerances and consistent part to part repeatability.
Commonly, the stainless steel should be cast by the investment precision casting process with the silica sol as the bond. The stainless steel silica sol castings have a very high grade of precision surface and performance.
Due to its unique physical properties, stainless steel castings are popular in a wide range of applications, especially those in harsh environments. Common markets for stainless steel investment castings include oil and gas, fluid power, transportation, hydraulic systems, food industry, hardware and locks, agriculture...etc.
Investment (lost wax) casting is a method of precision casting complex near-net-shape details using replication of wax patterns. Investment casting or lost wax is a metal forming process that typically uses a wax pattern surrounded by a ceramic shell to make a ceramic mold. When the shell dries, the wax is melted away, leaving only the mold. Then the casting component is formed by pouring molten metal into the ceramic mold.
The process is suitable for repeatable production of net shape components from a variety of different metals and high performance alloys. Although generally used for small castings, this process has been used to produce complete aircraft door frames, with steel castings of up to 500 kgs and aluminium castings of up to 50 kgs. Compared to other casting processes such as die casting or sand casting, it can be an expensive process. However, the components that can be produced using investment casting can incorporate intricate contours, and in most cases the components are cast near net shape, so require little or no rework once cast.
Silica sol casting process is the main steel investment casting process of RMC investment casting foundry. We have been developing new technology of adhesive material to achieve much more economical and effective adhesive material to build the slurry shell. It is a overwhelming trend that Silica sol casting process replaces the rough inferior water glass process, especially for stainless steel casting and alloy steel casting. Besides the innovated molding material, the silica sol casting process has also being innovated to much steadier and less heat expanding.
