Used after hardening, this furnace heats already-hardened metals to a lower temperature (e.g., 400°C for many steels) to reduce brittleness and relieve internal stresses while retaining most of the hardness. The working principle involves precise temperature control at these moderate temperatures to achieve the desired balance of toughness and hardness. Its purpose is a critical second step in the heat treatment of tools, springs, and structural components, making them less prone to catastrophic failure in service. Temperatures and times are carefully selected based on the steel grade and application.
This configuration is suitable when the sample load must fit a 885 x 830 x 830 MM chamber with usable chamber volume of 609.7 litre, approximate power load of 38.7 kW, rectangular - wide chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
