01
Normalising
Refines grain structure and promotes uniform mechanical properties.
Industrial Casting Heat Treatment
At Knights Foundry, we specialise in precision heat treatment to enhance the strength, durability and performance of our metal products. The Wadeville plant operates four heat treatment furnaces, including Tophat and low-temperature convection systems, with hardening capability up to 1100°C.
Plant Heating Systems
Tophat Heat Treatment
We use Tophat furnaces that bring the heat to the material, ensuring uniform temperature distribution.
Precision Convection Heating
Our low-temperature convection furnaces deliver efficient heat transfer with minimal thermal stress.
High-Temperature Hardening
Operating at temperatures up to 1100°C, we strengthen metals for high-performance applications.
Heat Treatment Processes
Four controlled metallurgical routes — applied to the casting specification so hardness, toughness and machinability land where the job needs them.
02
Hardening
Increases hardness, strength and wear resistance through controlled quenching.
03
Annealing
Softens material where required and can improve machinability.
04
Tempering
Balances required hardness with reduced brittleness after hardening.
