Our Sealed Quench Furnace is ideal for the heat treatment of components like gears, shafts, crankshafts, pins, bolts, fasteners, and tool & die parts. It offers a controlled environment for carburising processes, which are critical for enhancing the mechanical properties of materials such as EN8, EN9, EN19, EN24, 16MnCr5, 20MnCr5, SAE 8620, and EN31. Carburising is used to add carbon to the surface of low-carbon steels to enhance their hardness and wear resistance, while keeping the core material tough and ductile. After carburising, tempering is performed to reduce brittleness and improve the toughness of the hardened surface. It also helps relieve internal stresses that may result from the quenching process. This furnace can perform other heat treatment processes, including 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.

The Sealed Quench Furnace is compatible for heat treatment of material grades like EN8, EN9, EN31, 16MnCr5, 20MnCr5, SAE 4140, and SAE 8620. This furnace ensures precise atmosphere control and uniform heating for consistent results. Whether strengthening automotive gears or hardening industrial tools, it excels in enhancing mechanical properties while minimizing distortion. In this Tempering is a crucial step that follows processes like carburising or case hardening, designed to relieve internal stresses, reduce brittleness, and enhance the overall toughness of components. Similarly, Austempering process ensures an optimal balance between hardness and ductility, making treated parts more durable and resistant to impact. This furnace can perform other heat treatment processes, including hardening, carbonitriding, normalizing, nitrocarburizing, nitriding, austempering, neutral hardening, annealing, and bright hardening.

Sealed Quench Furnace (SQF) is used for high-precision heat treatment primarily in auto components industry. This allows heat treatment for carbon steel to reach the desired hardness and strength. The furnace feature allows the materials to be processed in batches rather than continuous operation. HIGHTEMP is the leading manufacturer of Sealed Quench Furnace in India that provides a global clientele, with sales volume exceeding 500+.
