Vacuum Aluminum Brazing of Radar Transceiver Box
The transceiver unit box is an important part of a radar system. Its function is to install and fasten all the electronic functional components in it, and provide it with a good ventilation, heat dissipation, electromagnetic compatibility and sealed three-proof working environment to ensure In it...
Quenching and Tempering of High Speed Steel in Vacuum Furnace
The characteristics of the quenching process of high-speed steel: mainly the high temperature of heating and quenching. The goal is to dissolve as much carbon and alloy into austenite as possible. The quenching methods of high-speed steel include oil quenching, grading, isothermal, and air coolin...
Effect of Vacuum Heat Treatment on Microstructure and Properties of Superhard High Speed Steel M2Al
M2Al is a kind of cobalt-free super-hard high-speed steel. Vacuum heating promotes abnormal grain growth. Filling with inert gas for vacuum heating can increase the heating speed, hinder the formation of abnormally large grains, and improve the strength and toughness of M2Al steel. The most impo...
High-speed Steel Tools & Vacuum High-pressure Gas Quenching Furnace
The heating and cooling of high-speed steel tools in vacuum has the effects of non-oxidation, non-decarburization, small deformation, bright surface and degassing, which can significantly improve product performance and extend the service life of tools and molds. Therefore, it has received widesp...
Spring Heat Treatment Quality Inspection and Operation Precautions
Spring heat treatment quality inspection includes inspection before heat treatment and inspection after heat treatment. 1. Quality Inspection Before Heat Treatment: The rolled surface of steel is often the surface after the spring is made, so there should be no cracks, folds, scars, hair lines, b...
The Role of Heat Treatment in The Reducer
Heat treatment is a very important link in the manufacture of reducer, but many users do not understand the role of this heat treatment, so in order to facilitate everyone’s understanding, the following is an introduction to its role. 1. Surface quenching: common surface quenching methods i...
The Main Factors Affecting the Degree of Graphitization of Cast Iron
Because the crystal structure of iron is very different from that of graphite, and the crystal structure of iron and cementite is closer, ordinary cast iron can only get white cast iron under normal casting conditions, but gray cast iron is not easy to obtain. Therefore, it is necessary to promot...
Advantages, Temperature and Time of Carbonitriding of Metallic Materials
1. Compared with gas carburizing, carbonitriding has the following advantages: 1) The same infiltration layer depth can be obtained at a lower temperature and in the same time; or at the same processing temperature, the co-infiltration rate is faster. 2) Carbonitriding does not precipitate carbon...
The Difference Between Austempering and Graded Quenching
Austempering: After heating the steel to make it austenitized and homogenized, it is quickly cooled to a certain temperature in a given bainite transformation temperature zone, and maintained at that temperature for a certain period of time to make it undergo isothermal transformation to form she...
Application of Metal Powder Injection Molding
Due to the use of injection molding, the metal forming process can produce very complex parts with various alloy materials. Its complexity far exceeds any metal forming process including other powder metallurgy processes, including: various external grooving, External thread, tapered outer surfac...
