Annealing: The Finishing Touch

We can provide quality magnetic heat treating - or annealing - to your order. While all steps prior to magnetic heat treating are important, the electrical property of laminations is of particular concern to every engineer and materials manager. The magnetic quality of steel has significant effect on performance.

Historically, fully-processed steel was the material of choice for transformers and motors. At Tempel, we have developed alternatives. Since magnetic performance is vital, Tempel has invested in the most advanced annealing facilities in the world. Precise, computer-controlled roller hearth furnaces ensure proper grain structure growth for lower core loss and improved permeability. The process also increases inter-laminar resistance by adding an oxide coating and relieves stamping stresses.

Our sophisticated annealing facility adds up to tangible advantages for our customers. At Tempel, you may effectively substitute more favorably priced, semi-processed electrical steel for expensive, fully processed electrical steels due to our advanced annealing capability. From these significant cost savings to quality improvements, our annealing process provides the ultimate in magnetic improvement for your lamination order.

Benefits: Since annealing enhances the electrical property of our laminations, they provide the highest performance available.
