Stainless Steel Castings

When you need stainless steel castings, you need a part or a product that can be relied on without question. In fact, in most cases you probably want a part or produce that you never have to think about again. With that in mind, one of our primary goals at Thompson Investment Casting is to produce the investment castings that you never have to second guess, stainless steel investment castings that make your life easier, and your products better.

Stainless Steel Casting Sizes, Tolerances, and Capabilities

Tolerance and Surface Finish
To deliver our signature level of quality and precision, we combine precision and our expertise with state of the art equipment that frequently achieves tolerances of +/-.005 per inch and surface finishes of 125 RMS or better.

With a variety of tools at our disposal, our size capability ranges from very small and intricate stainless castings weighing as little as a fraction of an once to equally detailed large stainless steel castings up to 25lbs, with a maximum size up to about 18 inches in length or width.

Wall Thicknesses
We understand that every application is unique, calling for stainless castings of every shape and size. Just as important as the size or weight of your casting is its wall thickness. With this need in mind, we've perfected the use of our modern vacuum assist process, enabling us to deliver wall thicknesses as thin as .020.

We frequently cast a wide variety of stainless steel alloys, including:

Extensive Secondary Operations: secondary operations performed at Thompson Investment Casting include machining, heat-treating, passivation, plating, black oxidizing, and painting.
