Would you like to know more information about one type steel for bits? (part 1)
The 20CrNiMo series steel is a widely used Cr-Ni-Mo surface-hardening steel, primarily applied in carburizing and carbonitriding processes. With relatively low contents of chromium (Cr), nickel (Ni), and molybdenum (Mo), this steel exhibits excellent forgeability, machinability, and weldability. ...Read more -
Installation and Use of Stabilizer
1.Introduction to the stabilizer The stabilizer is a cementing tool that is easy to manufacture, has a beautiful structure, is sturdy and durable, and has a strong straightening force. It overcomes the shortcomings of the original welded stabilizer, which is prone to detachment, and is a stabiliz...Read more -
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 -
Raw Materials for Forging
1.Common types of raw materials 1) Carbon steel and alloy steel: Carbon steel: including various components of carbon steel, it is one of the most commonly used raw materials in forging. Alloy steel: a mixture of metal and one or more metal or non-metal elements, characterized by high strength, g...Read more -
Forging inspection
Quality checks The quality inspection items of forgings are as follows: (1) Geometry and size Generally, the external dimensions of forgings are tested with measuring tools such as steel rulers, calipers, and templates; Die forgings with complex shapes can be accurately inspected using the markin...Read more -
