Heat Treating Investment Castings

Aug 22, 2023

To achieve the optimal performance and characteristics of precision cast parts, foundries will often utilize the heat treating of investment castings. In many cases, this is a critical part of the production process. Once the casting has been set, it can be subjected to temperatures of 3,000° F or higher. This alters the molecular structure and the alloy’s properties. Heating combined with either rapid or slow cooling can greatly increase the metal’s structural consistency, strength, ductility, and other critical characteristics. It is important to have an experienced metallurgist directing the heat-treating process.
