Shearing Tool Heat Treatment Process
Shearing tools are generally made of T10, 9CrSl, 6CrW2Si, H13 alloy steel and other materials. Processing before heat treatment: After forging, carbide unevenness is less than or equal to grade 6 Technical requirements: hardness HRC63~66 Heat treatment process: The first preheating: 500~550℃, 120...
Heat Treatment Of Food Machinery Knives
1.The development of heat treatment of food machinery knives With the continuous development of the processing technology of metal cutting machine tools, many advanced processing technologies have been introduced in blade processing, which has effectively improved the automation degree of blade ...
Precision Carburizing Heat Treatment of Gears and Requirements For Control Accuracy
1. Precision carburizing heat treatment requirements (1) The precision heat treatment of gear includes the microstructure, hardness, effective hardening depth, residual stress of carburized layer, and the quality dispersion of tooth profile and tooth direction. (2) Basic conditions required for p...
Why do Carbide Tools Achieve Higher Metal Removal Rates?
1. Production of carbide inserts As more and more advanced industrial equipment with cutting-edge automation and computer control enter the cemented carbide manufacturing enterprises, the technical control of the cemented carbide production process is becoming more and more stable, controllable a...
Summary of Heat Treatment Process Knowledge of Powder Metallurgy
1. Heat treatment process of powder metallurgy materials The heat treatment of powder metallurgy materials should be determined according to their chemical composition and grain size. The existence of pores is an important factor. During the process of pressing and sintering powder metallurgy mat...
Vacuum Heat Treatment of 65Mn Steel Sheet Spring Support
Material: 65Mn steel Technical requirements: the suture gland on the plane of the frame and the edge of the bracket should not exceed 0.2mm The 0.3mm thick 65Mn spring sheet is the button bracket used to select the channel on the TV [see Figure 1(a)]. The elastic parts require uniform structure d...
Vacuum Brazing Defects and Their Solutions
The main phenomena of vacuum brazing defects are: 1. Dissolution Dissolution is a depression formed on the surface of the base metal by the melting of the molten solder. (1) Causes of corrosion: The brazing filler metal does not match the brazing base metal, and a low melting point phase is forme...
The Principle of Aluminum Alloy Vacuum Brazing
There is a dense and very stable oxide film Al2O3 on the surface of the aluminum alloy, which is the main obstacle for the molten solder to wet the base metal. It is difficult to remove the oxide film by simply relying on vacuum conditions, and some metal activators, such as magnesium Mg, bismuth...
Vacuum Carburizing of Extrusion Die for Wire Take-up Connecting Rod Made of Base Steel 65Nb
Material: 65Nb steel Technical requirements: the mass fraction of carbon in the carburized layer is not more than 0.95%, Not more than 1.25% and about one-third of 1.6%, mesh and massive carbides are not allowed, and the depth of the carburized layer is about 0.6mm. The internal combustion type ...
Typical Heat Treatment and Tempering Process of W18Cr4V Steel
The purpose of tempering is to precipitate dispersed M2C and MC carbides from m, produce secondary hardening effect and eliminate residual austenite and internal stress. High tempering temperature is to improve the secondary hardening effect; More tempering times. On the one hand, the secondary h...
