Special Processes
At Kentucky Electric
Steel special processing can be provided. This one-step approach to
purchasing your material eliminates your handling until the product
is received to your specification.
Heat Treatments Available
Heat treating changes the properties of the bar. Heat treatments available include:
Annealing
Softens the steel and makes it more workable for shearing, forming and
machining.
Normalizing
Refines the internal structure of the hot rolled bar. The resultant surface has more uniform mechanical properties, better ductility and greater impact resistance.
Spheroidization Annealing
High temperature annealing process to make the structure more globular. This improves machinability and cold forming characteristics.
Quench & Temper
Changes the structure to martensite which improves toughness, strength
and ductility.
Thermal Stress Relieving
Removes residual stresses within the bar restoring mechanical properties and preventing distortion
Additional Processing Available:
- Saw Cutting
- Shot Blasting
- Oiling
- Special Straightening
- Special Packaging
