Top 10 Tempering Furnace Manufacturers Worldwide

Aug 05, 2026

A Tempering Furnace is an industrial heat treatment furnace used to heat hardened steel and other metal components to a controlled temperature below the critical transformation point, followed by controlled cooling. The process reduces excessive hardness and internal stresses after quenching while improving toughness, ductility, dimensional stability, and overall mechanical performance.

Tempering furnaces are widely used for:

Gears and shafts

Springs and fasteners

Dies and molds

Steel forgings and castings

Automotive components

Mining and construction machinery

Tool steels

Aerospace and railway components

Depending on workpiece size, production volume, and process requirements, tempering furnaces are available in box type, trolley type, pit type, mesh belt type, continuous, and atmosphere-controlled configurations.
