Stainless Steel Investment Casting
Our Expertise of Stainless Steel Investment Casting
We are very experienced in stainless steel investment casting. With strong capability of casting a wide variety of stainless steel alloy, we provide custom stainless steel investment casting parts and components for industries and applications including automotive, food & dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine and others. We can assure you high quality stainless steel investment castings. The sizes of the stainless steel casting parts range from 0.1 inch up to 24 inches. The weights of the stainless steel investment casting parts are from an ounce to 50 pounds. Typical tolerances are ± .005” per inch.
We work with our customers to assure that the stainless steel investment casting products/components can be manufactured with the desired characteristics in the most cost effective manner. Using simulation software to provide a “virtual prototype” we can begin to optimize the design prior to supplying products/components for design validation. We strive to be our customers’ best stainless steel investment casting supply chain partner.
For your stainless steel investment castings needs, we can help you out.

What Is Stainless Steel Investment Casting?
Stainless steel investment casting refers to the formation of ceramics around a wax pattern to form a shell for casting stainless steel. Once wax patterns are created, they are melted into the gate system, immersed in slurry and sand to form a layered shell, and then replaced by molten stainless steel.
How are Stainless Steel Investment Castings Made?
Stainless steel investment casting involves creating an original wax model, building the image with plaster and successive layers until a strong shell surrounds the model. After melting the wax, pour the molten stainless steel into the mold to create a perfect replica of the original wax pattern. Stainless steel investment casting provides economical undercutting, high resolution, sophisticated detail and smooth surface finish compared to machining separations.
In most cases, stainless steel investment casting is the only way the part can be made economically.

Stainless Steel Investment Casting Material Information
Material | Grade | Common Application |
---|---|---|
Stainless Steel | 304 | Housings, bodies. SS304 is widely used in medical, plumbing, watering, mining and petrochemical industries as the standard for cleanliness as well as corrosion resistance. |
316 | Housings, gears, plates. Superior corrosion resistance of SS316 makes it ideal for many applications including automotive, food & diary and petrochemical environments. | |
304L/316L | Similar to other 300 series steel, low carbon makes it softer but more corrosion resistant. Ideal industries are such as food & dairy, medical and petrochemical. | |
410 & 416 | Housings, bushings, handles, brackets. 400 series steels are high strength and very machinable. They will tend to break rather than bend under intense pressure. Ideal industries are automotive, food & dairy and various machine tools. | |
17-4 | Very strong. Can be used in military, various machine tools etc. |
