Overview

Heat treatment is often used to improve the mechanical and physical properties of castings. The processes can considerably increase the strength of components, as well as providing a range of other benefits.

What is Heat Treatment?

At LEWIS, we carry out heat treatments in a highly controlled manner to ensure that the completed product complies with the required specification. The use of specialist furnaces allows temperatures to be kept within strict parameters. This ensures that the casting retains its shape and doesn’t crack.

There are a variety of heat treatment processes available. This allows us to achieve the different properties necessary for a range of applications.

Once the casting has been heat treated, it is tested for hardness. This is measured on the Brinell scale, which is a nationally recognised standard.
