The difference between high-speed steel and tungsten steel is very clear!
Come to understand high speed steel High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as wind steel or front steel, which means that it can be hardened even when it is cooled in air during quenching, and it is very sharp. It is al...Read more -

The basic knowledge of thread gauge, you can earn it when you see it
Basic knowledge of thread gauges A thread gauge is a gauge used to test whether a thread complies with regulations. Thread plug gauges are used to test internal threads, and thread ring gauges are used to test external threads. Thread is an important and commonly used structural element. Threads ...Read more -
A complete collection of steel knowledge, good things are to be shared! !
1. Mechanical properties of steel 1. Yield point (σs) When the steel or sample is stretched, when the stress exceeds the elastic limit, even if the stress does not increase, the steel or sample still continues to undergo obvious plastic deformation. This phenomenon is called yielding, and the min...Read more -

（1） Start up 1. Turn on the power switch on the front panel and set the power switch to the “ON” position. The power light is on. The fan inside the machine starts to spin. 2. The selection switch is divided into argon arc welding and manual welding. （2） argon arc welding adjust...Read more -
What welding method should be used for welding iron, aluminum, copper and stainless steel
How to weld mild steel? Low carbon steel has low carbon content and good plasticity, and can be prepared into various forms of joints and components. In the welding process, it is not easy to produce hardened structure, and the tendency to produce cracks is also small. At the same time, it is n...Read more -
How to distinguish molten iron and coating during manual arc welding
If it is manual arc welding, first of all, pay attention to distinguish molten iron and coating. Observe the molten pool: the shiny liquid is molten iron, and what floats on it and flows is the coating. When welding, pay attention to not let the coating exceed the molten iron, otherwise it is eas...Read more -
The origin of CNC tools, unimaginable greatness of human beings
The development of knives occupies an important position in the history of human progress. As early as the 28th to 20th centuries BC, brass cones and copper cones, drills, knives and other copper knives had appeared in China. In the late Warring States period (third century BC), copper knives wer...Read more
