Tempering Ovens and Furnaces

A tempering oven or furnace is used extensively during the metal tempering process to increase the strength of iron-based alloys like cast iron and steel. Metals are placed in a tempering oven and then heated to a specific temperature in order to remove unwanted or excess hardness.

Utilizing heat treatment techniques applied to ferrous alloys, metal tempering furnaces are used in the metallurgy process to achieve greater toughness in a material while decreasing the hardness of the alloy.

What Is The Difference Between Toughness and Hardness When Tempering Steel?

The two states at play when tempering steel in an oven are toughness and hardness. On the surface, those terms would seem interchangeable, but in metallurgy, they are distinct properties of an alloy.


Defining Toughness in an Alloy

In metallurgy, — the branch of science and technology that deals with the study of metals — and other materials science, toughness is a material’s ability to absorb energy and deform plastically without fracturing completely. Another way to think about toughness would be to define it as a material’s resistance to fracture. Metal tempering ovens are used to achieve higher toughness in an alloy to prevent catastrophic failure by allowing for deformation instead of fracturing.

Hardness in an Alloy Composition

Hardness, by contrast, is how resistant to plastic deformation a material is. The higher a composition’s hardness rating, the less likely it is to deform when placed under force. Tempering furnaces reduce hardness by heat-treating the metal in order to develop more toughness.

How Tempering Furnaces Are Used

A factory-tech tempering oven is used primarily to increase the toughness of metal or cast iron tools by decreasing the hardness of these products. The tradeoff is beneficial for the overall performance of a given part. These industrial tempering furnaces offer a range of temperatures because the amount of hardness removed depends on the metal’s composition and the desired outcome of the product.

How Hot Does A Tempering Oven Get?

The temperature for a tempering oven is typically about 1,148° Fahrenheit or 620° Celsius.

However, tools and similar materials are tempered at lower temperatures because material hardness is a benefit to their overall performance. Products like springs require higher temperatures inside of an oven to allow for more material deformation and plasticity.
