At Kilner & Hutchinson, we've invested heavily in our West Yorkshire site to ensure we can deliver every element of our high integrity castings in-house. Providing heat treatment of castings ourselves means we are able to maintain control of the process from start to finish.
The controlled heating and cooling of metals allows us to alter the properties of the component without any change to the shape. Extreme temperatures can harden, strengthen and soften a metal, enhancing performance to your exact specifications.
Types of heat treatment
There are four main types of heat treatment used in cast iron and steel production:
- Hardening makes cast iron stronger and harder, but less flexible and more brittle.
- Tempering makes hardened metals less brittle following the hardening process.
- Annealing softens metal components, making them more pliable and fixing weak spots.
- Normalising removes the stresses caused to the metal by other production methods.
Many components will go through all four processes for the best possible finish.
