Carbon Steel Investment Castings

Carbon Steel Investment Castings

Looking for cost savings? Carbon steel investment castings may be the answer. Because we provide carbon steel investment cast parts to net shape, we can eliminate most, if not all secondary machining operations.

Providing a net shape to typical casting tolerances of +/-.005" per inch, Milwaukee Precision Casting, Inc. has proved time and time again that sand castings, forgings, and machined components can be converted to carbon steel investment castings with significant cost savings.

Popular Carbon Steel Grades

Carbon Steel Investment Casting Grades

Alloy Common Usage Applications

1018 & AISI 1020

The 1000 series is the softest of the three common carbon steels will more likely bend rather than break under intense pressure. They are commonly used to make cranks, handles, and braces.

Machine Tool




SAE 4140 & 4140 MIL-S

The 4100 series is a high strength material that is used when deformation of a part is not allowed. They are commonly used to cast firearm components and ratchets.




SAE 8620

The 8600 series steel is the middle ground between 4100 and 1000 series. 8600 series is stronger than 1000 series but will bend prior to breakage. They are commonly used to cast firearm components, housings, and nozzles.
