This furnace is optimized for the complex heat treatment cycles required by tool steels (e.g., H13, D2), which involve hardening at high temperatures and multiple tempering steps. Operating up to 1000°C or more for hardening, it requires precise atmosphere control to prevent decarburization. The working principle ensures uniform heating to the specific austenitizing temperature of the grade, followed by controlled quenching and precise tempering. Its purpose is to produce durable dies, molds, cutting tools, and punches that can withstand high stress, abrasion, and impact in manufacturing.
This configuration is suitable when the sample load must fit a 125 x 125 x 250 MM chamber with usable chamber volume of 4 litre, approximate power load of 5 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 1000 Degree Celsius (°C) Tool Steel Heat Treatment Furnace 125 x 125 x 250 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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.
