Manufacturers teach you how to distinguish the material of stainless steel wire mesh
Stainless steel wire mesh is widely used in the market. There are many types of products, which are very popular among new and old customers. The stainless steel wire mesh itself has many product advantages, and the quality and safety are guaranteed. The following is a key introduction to the material characteristics of stainless steel wire mesh.
The characteristics of stainless steel wire mesh have the following points:
1. Stainless steel wire mesh has high strength, strong tensile strength, toughness and wear resistance, durability and long service life;
2. Stainless steel wire mesh is resistant to high temperature oxidation in production. The nominal temperature of 304 stainless steel wire mesh is 800 degrees Celsius, and the nominal temperature of 310S stainless steel wire mesh can reach 1150 degrees Celsius.
3. Stainless steel wire mesh has acid resistance, alkali resistance and rust resistance;
4. The stainless steel wire mesh has high finish, no surface treatment, and convenient and simple maintenance;
The material of the stainless steel wire mesh is divided into the following methods:
1. Stainless steel wire mesh can be distinguished from toughness. 304 has better toughness. 201 is harder than 304. It is hard to use a hard knife to make an experiment. After the surface of 201 is scratched, there will be obvious scratches, while the surface of 304 There will be no obvious scratches.
2, stainless steel wire mesh can be from acid and alkali resistance, 201 due to the relatively small content of nickel, acid and alkali resistance is not good 304.
3. Stainless steel wire mesh can be rusted due to the corrosion resistance. Since 201 contains manganese, it will rust in a humid or salty environment for a long time, and 304 will not rust because it does not contain manganese.
4, stainless steel wire mesh can be seen from the color, because 201 stainless steel contains manganese color will be darker than 304, and 304 should be white and bright.
The above is the characteristics of the non-exhibition steel mesh and how to distinguish it from the material.
Stainless steel wire mesh occasionally blacks out during use. What is the cause? This is still related to the constituent elements of the original material. Let's analyze the blackening phenomenon of the stainless steel wire mesh together.
The main elements of stainless steel are iron, nickel and chromium. These are the alloy products of these three metals. The three metals can be produced in different proportions. The obtained stainless steel products also have different properties and different appearances. When the iron content is constant, the higher the chromium content, the brighter the stainless steel wire, and the higher the nickel content, the darker. If the content of chromium and nickel does not change, the content of the paste will also become darker, which is the judgment of the initial appearance of the product.
If blackening occurs during use, it is caused by oxidation, that is, the iron contained in it is oxidized by heat and becomes black quickly, showing no signs of rust.
In addition, in the production process, the wire drawing machine is not well lubricated, the frictional resistance is too large, and the surface of the stainless steel wire mesh is seriously heated, causing segregation of the metal elements inside the wire, and the alloy is analyzed, and the surface is blackened.
We can see that the reason why the stainless steel screen is black is not single. To solve this problem, we need to solve it in many aspects.
