This furnace is specifically for hardening ferrous metals, particularly steel, by heating them to a critical temperature (typically 850°C for many steels) and then rapidly quenching in oil, water, or polymer. The working principle involves a chamber that heats the parts uniformly to the austenitizing temperature, followed by a quick transfer to a quench tank. Its purpose is to increase the hardness and wear resistance of components like tools, gears, and bearings. It is a fundamental piece of equipment in heat treatment shops and manufacturing plants.
This configuration is suitable when the sample load must fit a 170 x 200 x 170 MM chamber with usable chamber volume of 5.8 litre, approximate power load of 5.9 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.

Trutherm manufactures 1400 Degree Celsius (°C) Hardening Furnace 170 x 200 x 170 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.
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.
