Pyradia supports a wide range of industrial processes, including adhesive coating, aluminum aging, composite curing, and more. Our advanced equipment and expertise ensure precise and reliable results for all applications.
Tempering is the heat treatment applied after quenching to reduce brittleness and improve toughness. The hardened steel is heated to a controlled temperature below its transformation point, then cooled.
Quenching hardens steel by rapid cooling; tempering, carried out afterwards at a lower temperature, reduces the brittleness that quenching leaves behind.
A lower tempering temperature preserves hardness; a higher one favours toughness. The exact temperature sets the final balance of mechanical properties.
Forced-air-circulation tempering furnaces, which deliver the temperature uniformity needed for repeatable results on single loads and production runs alike.
Almost always for steel: without tempering, a quenched part stays too brittle for practical use. Tempering stabilizes the microstructure and the residual stresses.
