- Tempering balances hardness with core toughness.
- Optimized design reduces energy consumption and operational costs.
- Suitable for medium- and high-carbon steels, alloy steels, and low-alloy steels


Carburising in a Sealed Quench Furnace is a highly efficient and controlled process that enhances the surface hardness of low-carbon steel components. By diffusing carbon atoms into the surface, this process creates a hard, wear-resistant outer layer while retaining a tough, ductile core. The sealed quench furnace ensures a precisely controlled carbon-rich atmosphere and uniform heating, resulting in consistent and high-quality results. Widely used in automotive, aerospace, and heavy machinery industries, carburising in a sealed quench furnace delivers superior mechanical performance, extended component life, and reliable results for demanding applications. This furnace can perform other heat treatment processes, including tempering, hardening, carbonitriding, normalizing, nitrocarburizing, nitriding, austempering, neutral hardening, annealing, and bright hardening.


The Sealed Quench Furnace is a high-performance heat treatment system designed for austempering, carburising, and tempering. Ideal for components like gears, shafts, clutch plates, springs, fasteners, and crankshafts, it delivers superior wear resistance, toughness, and fatigue strength. Austempering is a specialized process that transforms steel into an ausferrite microstructure, enhancing toughness, wear resistance, and fatigue strength with minimal distortion. This makes it ideal for components that require superior mechanical performance. This furnace can perform other heat treatment processes, including hardening, carbonitriding, normalizing, nitrocarburizing, nitriding, neutral hardening, annealing, and bright hardening.
