How to distinguish the material of stainless steel wire mesh
For stainless steel wire mesh, we are already very familiar with the advantages and advantages of stainless steel wire mesh.
The characteristics of the stainless steel wire mesh are as follows:
High strength, strong tensile, toughness and wear resistance, durable;
High temperature oxidation resistance, 304 stainless steel wire mesh nominal temperature resistance is 800 degrees Celsius, 310S stainless steel wire mesh nominal temperature can reach 1150 degrees Celsius;
Good acid resistance, alkali resistance and rust resistance;
High finish, no surface treatment, easy maintenance;
Normal temperature processing, that is, easy plastic processing, makes the use of stainless steel wire mesh diversified. Generally speaking, the material of stainless steel wire mesh should be 304 material, but some black heart manufacturers may use 302 or 201 to impersonate 304 in order to make more money. The 302 or 201 and 304 materials are difficult to distinguish with the naked eye. How can we tell? Today, Xiaobian will briefly introduce the method of distinguishing the material of stainless steel wire mesh.
The chemical formula of 201 is 1Cr17Mn6Ni5, and the chemical formula of 304 is 0Cr19Ni10; the main difference between them is nickel-chromium element, 201 is 17 chromium, 5 chromium-nickel element also contains 6 manganese elements, and 304 is 19 chromium elements and 10 nickel elements; So they cause many differences in color, corrosion resistance, acid and alkali resistance, toughness and so on. Next, we will introduce the method of distinguishing the material of stainless steel wire mesh.
The method for distinguishing the material of stainless steel wire mesh is as follows:
1. From the perspective of toughness, the toughness of 304 is better, 201 is harder than 304, and the experiment is done with a hard knife. After the surface of 201 is scratched, there will be obvious scratches, and the surface of 304 will not be obvious. Scratches.
2, from the acid and alkali resistance, 201 due to the relatively small content of nickel, acid and alkali resistance is not good 304.
3. In terms of corrosion resistance, since 201 contains manganese, it will rust in a humid or salty environment for a long time, and 304 does not rust because it does not contain manganese.
4, from the color point of view, because 201 stainless steel contains manganese, the color will be darker than 304, and 304 will be white and bright.
The above are four ways to distinguish the material of stainless steel wire mesh. Have you learned it? In the process of buying stainless steel wire mesh, be sure to polish your eyes and buy a real stainless steel wire mesh.
