This furnace is specifically optimized for the hardening process of metal components, particularly steel. It heats parts to their austenitizing temperature (typically 850°C for medium-carbon steel) in preparation for quenching. The working principle ensures rapid, uniform heating to the precise temperature needed to transform the microstructure, often with atmosphere control to prevent decarburization. Its purpose is to produce parts with high surface hardness and wear resistance, such as tools, dies, gears, and automotive components, which are then tempered to reduce brittleness.
This configuration is suitable when the sample load must fit a 150 x 150 x 300 MM chamber with usable chamber volume of 6.8 litre, approximate power load of 6.2 kW, square 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 1200 Degree Celsius (°C) Metal Hardening Furnace 150 x 150 x 300 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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.
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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
