Metal Hardness Test Method
The hardness of a metal refers to the resistance to plastic deformation caused by the intrusion of foreign objects in a local volume of the metal surface. The higher the hardness, the stronger the resistance of the metal to plastic deformation, and the more difficult it is for the metal to produc...
What Heat Treatment Should be Carried Out Before Nitriding Steel Parts?
Nitriding is the last step in the manufacturing process of parts. After the workpiece is nitrided, only fine grinding or grinding is performed. In order to ensure that the core has good comprehensive mechanical properties, eliminate processing stress, reduce nitriding deformation, and prepare for...
Deformation Control of Carburized Gear Heat Treatment
The heat treatment deformation of carburized gear directly affects the accuracy, strength, noise and life of the gear. Even if the gear grinding process is added after the carburizing heat treatment, the deformation will still reduce the precision level of the gear. There are many factors that af...
Several Commonly Used Stainless Steels and Their Heat Treatment Properties
According to the structural composition of the steel after normalizing heat treatment, it can be divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel and transition stainless steel (semi-austenitic stainless steel, that is, both austenitic and The advanta...
What Are the Types of Gear Heat Treatment?
1. Gear normalizing heat treatment Normalizing treatment can eliminate excessive stress inside the gear, increase the toughness of the gear, and improve the cutting performance of the material. Normalizing is often used for gears made of high-quality carbon steel or alloy steel with a carbon cont...
