Comparison of 201 stainless steel mesh and 304 stainless steel mesh

The material of stainless steel mesh should be SUS304. But there are many bad manufacturers in order to reduce the cost of 201 stainless steel instead of 304 stainless steel.

Stainless steel meshes 201 and 304 are difficult to distinguish from the naked eye of ordinary people. In order to prevent more bad manufacturers from continuing to blind our shaker users and disrupt the market order, this will affect user use and production.

 Material discrimination method: The chemical formula is 1Cr17Mn6Ni5,304 and the chemical formula is 06Cr19Ni10; the main difference between them is the nickel chromium element, the stainless steel mesh 201 is 17 chromium 5 chromium nickel elements also contains 6 manganese elements, 304 is 19 chromium elements Nickel element; so they make a lot of difference in color, corrosion resistance, acid and alkali resistance, toughness and so on.

From the color point of view, because 201 stainless steel contains manganese, the color will be darker than 304, and 304 will be whiter and brighter. In terms of corrosion resistance, because 201 contains manganese, it will rust in a long time in a humid or salty environment. Stainless steel mesh and 304 will not rust because it does not contain manganese.

In terms of acid and alkali resistance, 201 has a lower nickel and acid and alkali resistance than 304. In terms of toughness, 304 has better toughness, and 201 is harder and more brittle than 304. Stainless steel nets are tested with a hard scribe. After the surface of 201 is scratched, there will be obvious scratches, but the surface of 304 will not be obvious. Scratches.
