Applications of hardenability and hardenability of forgings
Hardenability and hardenability are the performance indexes that characterize the quenching ability of forgings, and they are also the important basis for selecting and using materials.Hardenability is the maximum hardness that a forging can achieve under ideal conditions.The main factor determin...Read more -
The way to improve the plasticity of forging and reduce the deformation resistance
In order to facilitate the flow forming of metal billet, reduce the deformation resistance and save equipment energy, the following methods are generally adopted in forging process: 1) Grasp the material characteristics of forgings, and select a reasonable deformation temperature, velocity and de...Read more -

What are the methods of forging cleaning
Forgings cleaning is the process of removing surface defects of forgings by mechanical or chemical means. In order to improve the surface quality of forgings, improve the cutting conditions of forgings and prevent the surface defects from enlarging, it is required to clean the blank and forgings ...Read more -
Defects and Countermeasures of large forgings: Uneven microstructure and properties
Large forgings, due to their large size, many processes, long cycle, non-uniformity in the process, and many unstable factors, often cause serious non-uniformity in the microstructure, so that they cannot pass the mechanical property test, metallographic inspection and non-destructive flaw detect...Read more -
Defects and Countermeasures of large forgings: Forging cracks
In large forging, when the quality of raw materials is poor or forging process is not at the right time, forging cracks are often easy to occur. The following introduces several cases of forging crack caused by poor material. (1) Forging cracks caused by ingot defects Most of the ingot defects m...Read more -
The forging process of ring forgings
Ring forgings are widely used in industry at present. The forging process of ring forgings is also composed of four parts. The following is mainly to tell you about some ring forging process, I hope you can learn. The forging process of ring forgings mainly consists of the following steps: Pier ...Read more -
The basic process of forging
The forging process of forgings is generally as follows: ingots preparation or blank blanking - ingots (blank) inspection - heating - forging - cooling - intermediate inspection - heat treatment - cleaning - final inspection after forging. 1. the ingot is mainly used for the production of medium ...Read more -
The influence of various metals on the properties and malleability of steel
Metals are thermoplastic and can be pressed when heated (different metals require different temperatures). This is called malleability. Malleability the ability of a metal material to change shape without cracking during pressure working. It includes the ability to perform hammer forging, rolling...Read more -
