Aluminum alloy vacuum brazing process
Due to the characteristics and advantages of vacuum brazing, it is widely used. If the vacuum brazing process is selected for complex and precise aluminum alloy brazing, the vacuum brazing process can be formulated for the brazing of such parts before brazing. And inspection rules, but also need ...
Vacuum heat treatment of 20CrMnTi steel
20CrMnTi is a low carbon alloy steel with high mechanical properties, and the surface of the parts is carburized 0.7-1.1mm. After carburizing quenching and low temperature tempering, the surface hardness is 58-62HRC, and the core hardness is 30-45HRC. The process performance of 20CrMnTi is better...
Vacuum Carburizing And Gas Quenching Process For The Input Shaft Of Precision Reducer
Vacuum low pressure carburizing and high pressure gas quenching process for the input shaft of industrial robot precision reducer Shaft tooth parts have a very wide range of applications in industrial technology. The structure of the input shaft of the industrial robot reducer is complex. One end...
The production process of diamond grinding disc brazing
The diamond grinding disc brazing production process has five processes: product preparation, pre-treatment, sanding and powdering, sintering and post-processing. 1, Product preparation process The main contents of the product preparation process are: matrix pressing, abrasive selection and bra...
Vacuum low pressure carburizing heat treatment process of 8620 steel
8620 alloy steel is an American steel grade. Its main composition is similar to that of domestic 20CrNiMo steel. It is often used in the forging of key components such as gear shafts, valves in pressure vessels, and inlet and outlet pipe seats. It has high hardenability and superior welding and p...
Vacuum Brazing Process
Vacuum brazing can be divided into high vacuum brazing and partial vacuum brazing according to different vacuum conditions. High vacuum brazing is suitable for brazing filler metals and base metals that contain less volatile elements and are difficult to decompose oxides. If the solder contains m...
Die steel vacuum quenching process
Cr12mov steel pipe is a cold work die steel. There are two heat treatment processes: the first process is called low quenching and low recovery. It is used in an environment where the operating temperature is not high and has good toughness. With the increase of tempering temperature, the hardnes...
Vacuum Brazing of Ceramic Metals
Engineering ceramics has developed into a generally recognized high-performance structural material due to its excellent high temperature resistance, corrosion resistance and wear resistance, but its application is limited due to its poor plasticity and impact resistance. Only by combining the st...
Vacuum oil quenching heat treatment
Vacuum quenching oil (requirements for quenching oil): (1) Low vapor pressure, not easy to volatilize; (2) There are few impurities and carbon residues, and the acid value is low; (3) Low critical pressure and good cooling performance; (4) good thermal stability; Characteristics of quenching oil ...
9SiCr die steel vacuum heat treatment
9SiCr steel is a kind of low alloy steel for cutting tools. It is widely used in China and is often used in cold work molds, which has played a very good role. Compared with chromium steel (Cr2 or 9Cr2), 9SiCr steel has higher hardenability and hardenability, and has excellent tempering stability...
