Screws must be commonplace for us. People who pay more attention to detail will pay more attention to the screws that are used to manufacture their own tools or equipment. What are the raw materials used to make us? What's the screw needed for the market (shì chǎng)? Such doubts will arise because we can only use it in detail when we find out about the details of a thing, and how we can avoid the process of using it (guò chéng). (attention) place.
Actually, if we go to the market and study it, we will know that the screws we use now are made of these three kinds of raw materials. They are carbon steel, stainless steel (stainless acid Steel), and copper these three metals. Because of their different characteristics, the screws made by them will also show different characteristics. Find out about their raw materials will give such and other tips for our use, find the source, and problem (Emerson ) And risk is well circumvented.
In carbon steel, a finer division of labor is often made based on the amount of carbon contained. The main purpose of the custom screws is to make the industrial products fixed and integrated. In use, it often happens that there is no close between the teeth and the teeth, if the screw head is broken too tightly, or the teeth are not tightly locked, the conditions are not met. The accuracy of the quality problem. There are medium-carbon steels, high-carbon steels, and alloy carbon steels of the other type, each with their own specifications and titles. The market is not very large in terms of the use of high-carbon steels. Basically, it will not be adopted. of.
Then the stainless steel (stainless acid-resistant steel) material quality screws, and we all know the material properties of stainless steel (stainless acid-resistant steel). Stainless steel screw refers to the shape of a screw made of stainless steel screw wire rod, and it is threaded in the rear. Its material is stainless steel. Stainless steel screws are divided into stainless steel SUS201 screws, stainless steel SUS304 screws, and stainless steel SUS316 screws. Corrosion resistance to heat and corrosion, suitable strength, for the welding process is very beneficial.
The last is the screw of copper products, mainly based on brass and new copper alloy materials (Material). Non-standard screws utilize the physics and mathematics of the object's bevel circular rotation and friction, and progressively fasten the tool's tools. Screws are a common term for fasteners, spoken daily.
Then the above is the raw material of the screws we see today (shì chǎng). They each have a wide range of use. For us, we should make different choices according to different needs (xuanze). It is a wise choice
