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.

A sealed quench furnace is a highly efficient, controlled atmosphere furnace designed for heat treatment processes such as hardening and tempering. It is widely used in the automotive and industrial sectors for components requiring superior mechanical properties and wear resistance. For the heat treatment of engine components such as connecting rods and valves made from materials like 4130, 4340, 42CrMo4, En-8D, A217, and A351 Hardening and Tempering process is implemented where the components are heated to their austenitizing temperatures in a controlled atmosphere to prevent oxidation and decarburization. Rapid quenching in oil or polymer quenchants, to achieve desired hardness and microstructure. Components are further reheated below the critical temperature to achieve the required toughness, ductility, and stress relief. This furnace can perform other heat treatment processes, including carburizing, , carbonitriding, normalizing, nitrocarburizing, nitriding, austempering, neutral hardening, annealing, and bright hardening..

HIGHTEMP Sealed Quench Furnace is the ideal solution for the carbonitriding and tempering of high-performance components, ensuring enhanced surface hardness, wear resistance, and toughness. This furnace is particularly effective for components such as gears, shafts, pins, bolts, fasteners, crankshafts, tool & die parts, and bearings. Using materials like EN8, EN9, EN19, EN24, 16MnCr5, 20MnCr5, SAE 8620, and EN31 (high-carbon steels), it ensures consistent, superior-quality heat treatment. Carbonitriding is a surface hardening process where carbon and nitrogen are diffused into the steel surface, improving its hardness, wear resistance, and fatigue strength. The sealed quench furnace ensures a controlled atmosphere to minimize oxidation and decarburisation. After carbonitriding, tempering is used to relieve internal stresses and reduce brittleness while retaining the hardness of the treated surface. This furnace can perform other heat treatment processes, including carburizing, hardening, normalizing, nitrocarburizing, nitriding, austempering, neutral hardening, annealing, and bright hardening.
