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.

Trutherm manufactures 1400 Degree Celsius (°C) Metal Tempering Furnace 130 x 170 x 205 MM Chamber for buyers who search by exact machine type, chamber size and 1400°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 130 x 170 x 205 MM chamber with usable chamber volume of 4.5 litre, approximate power load of 5.3 kW, rectangular - tall 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
