The importance of brazing holding time
The brazing holding time is an important stage for the filler metal to fill the gap and control the alloying effect, and the effect on the joint strength is similar to that of the brazing temperature. A certain holding time is necessary for the mutual diffusion of the solder and the base metal to...
Low pressure vacuum carburizing process of Cr17Ni2 stainless steel
Materials The Cr17Ni2 stainless steel parts are used as connecting rods, and the furnace sample is a ring sample with an outer diameter of q24 mm, an inner diameter of 7 mm, and a thickness of 6 mm. The furnace sample is the test sample. After carburizing, the surface hardness is required to be ≥...
Vacuum heat treatment of high speed steel
High-speed steel originated at the end of the 19th century. It is a high-carbon and gold-containing cutting tool steel containing a large amount of W, Mo, Cr, V, Co and other alloying elements. After vacuum heat treatment, high-speed steel still maintains high hardness at a high temperature of 60...
Battery cooler vacuum brazing
Vacuum brazing is to heat and heat the structural parts in a vacuum state, so that the brazing filler metal melts within a suitable temperature and time range, and fully infiltrate, dissolve, diffuse and weld with the solid metal under the action of capillary force, so as to achieve An advanced w...
Vacuum heat treatment furnace for copper alloys
The vacuum heat treatment of copper alloy is mainly heating and vacuum annealing for different purposes. Only alloys of individual grades, such as bronze plating, can be vacuum quenched and vacuum tempered. Annealing for different purposes are: softening annealing, finished annealing and billet a...
Martensitic stainless steel vacuum sintering heat treatment
As a special steel with high alloy content, martensitic stainless steel has become an indispensable material in engineering and daily life. Adding carbon to chromium-containing steel expands the austenite, making it like carbon steel to transform austenite into martensite through heat treatment, ...
MIM vacuum sintering furnace
Over the past 30 years, metal injection molding (MIM) technology has produced increasingly complex parts and its applications have covered a wide variety of different industries. With the growing market demand for high-quality parts with low geometric deformation and strong material properties, t...
Martensitic stainless steel quenching vacuum heat treatment process
Martensitic stainless steel is a type of stainless steel whose properties can be adjusted by vacuum heat treatment (quenching, cryogenic, tempering). Martensitic stainless steel has high strength and corrosion resistance, and can be used to manufacture machine parts such as blades of steam turbin...
Vacuum Heat Treatment of Hollow Linear Optical Axis
There are solid and hollow linear optical axes, and the structure and performance of the two are different. In contrast, the weight of the hollow linear optical shaft is definitely much lighter, so the self-weight of the shaft is also reduced a lot, so that the effect of the transmission torque o...
Precision gear vacuum heat treatment
The vacuum heat treatment of gears includes vacuum heating and quenching and vacuum chemical heat treatment. Low-pressure vacuum carburizing and high-pressure gas quenching technology are used in the heat treatment of precision automobile gears to obtain smaller gear heat treatment deformation an...
