Surface treatment of forging
Many mechanical parts work under alternating loads and impact loads such as torsion and bending, and their surface layers are subjected to higher stress than the core; In the case of friction, the surface layer is constantly worn out. Therefore, the requirements for strengthening the surface laye...Read more -
A Steel Material For Drill Bits (Part 2)
3.3 High Magnification Examination Samples are taken from the R/2 position of the rolled steel bars. These samples are subjected to tests for non-metallic inclusions, austenite grain size, and banded structure. Furthermore, the microstructure of the samples is analyzed in detail under a microscop...Read more -

What is the Validation of Heat Treatment Process?
Heat treatment is a controlled process used to alter the physical and sometimes chemical properties of materials, particularly metals and alloys, to achieve desired characteristics such as increased strength, hardness, or ductility. The validation of the heat treatment process ensures that the pr...Read more -
The Purpose of Heating Before Forging
1. The main purpose of pre-forging heating is to improve the plasticity of the metal l Heating can intensify the atomic vibration inside the metal, weaken the bonding force between atoms, thereby increasing the plasticity of the metal and making it easier to deform. l Reduce deformation r...Read more -
Introduction to Screw Drilling Tools
Screw drilling tools, also known as progressive cavity type positive displacement bottom hole power tools, are commonly referred to as screw drills. These tools deliver drilling mud or water through the central hole of the drill string as a power medium, converting the pressure energy of the flui...Read more -
