Horizontal Type Gas Nitriding Furnace
Horizontal type gas nitriding furnace is a cycle-operated heat treatment electric furnace, mainly for steel parts and auto spare parts for gas nitriding. Due to the selection of ultra-lightweight energy-saving furnace lining materials and advanced integrated water-cooling furnace sealing fans, th...
Differences in vacuum heat treatment between aerospace blanks and parts
Generally speaking, the ex-factory and incoming inspection of materials is carried out by cutting a small amount of physical and chemical materials from the rough material. The heat treatment system is carried out according to the system or strength grade requirements specified in the material st...
Step shaft vacuum quenching heat treatment
Shafts are rotating mechanical elements, usually of circular cross-section, that utilize stepped shoulders to locate mounting parts of different inner diameters, such as gears, bearings, etc. The stepped shaft mainly locates the installed parts. The shoulders of different heights can limit the mo...
High speed steel vacuum heat treatment
The vacuum heat treatment of high-speed steel has developed rapidly because of the vigorous promotion of green and low-carbon life. Many professional tool factories and heat treatment factories have successively established vacuum heat treatment workshops, and the quantity and variety of products...
Vacuum Heat Treatment and Nitrocarburizing of Hot Work Die Steel 4Cr5MoSiV1
On the plastic mold, the push rod (referred to as EPN) made of 4Cr5MoSiV1 hot work mold steel works under the condition of alternating mechanical load and working temperature. In order to improve its fatigue resistance, it must have high thermal fatigue resistance, high yield point, high fracture...
Vacuum annealing process of automobile half shaft
1.Half shaft The half shaft is also called the drive axle. The half shaft is a solid shaft that transmits torque between the differential and the drive wheel. The half-shafts commonly used in modern automobiles have two types, full-floating and semi-floating, according to their different bearing ...
Differential ring gear vacuum heat treatment
The automobile differential can make the left and right (or front and rear) drive wheels rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when th...
Advantages of vacuum sintering of cemented carbide
Vacuum Sintering: Powder sintering under sub-atmospheric pressure conditions. Mainly used for sintering active metals and refractory metals beryllium, thorium, titanium, zirconium, tantalum, niobium, etc.; sintering cemented carbide, magnetic alloys, tool steel and stainless steel; A compound th...
Vacuum heat treatment of aerospace aluminum alloy materials
Aerospace aluminum alloys mainly refer to: military aircraft, civil aircraft, spacecraft, and launch vehicles. In aircraft materials, aluminum materials account for more than 80%. Typical aerospace aluminum alloy products: pre-stretched sheet 7075, skin sheet, forgings, large integral wall panels...
Gear vacuum carbonitriding
Gas carbonitriding is a traditional heat treatment technique that was extensively studied in the 1960s and widely used in the 1970s. Due to the infiltration of nitrogen, the critical point (Ai, As) of the steel is moved down by this technology, which can appropriately reduce the quenching tempera...
