How to identify the material quality of stainless steel mesh.

Three major ways to identify the material of stainless steel wire mesh: one is the nickel content, the other is chemical testing method, the third is considering the prices.

One method is to identify the stainless steel wire mesh quality from the nickel content.

Pricing of stainless steel wire mesh depends on material, mesh, unit weight and other factors. Take stainless steel screen of 80 mesh for example, the cost for high quality ss wire mesh is about USD 6-7 per square meter, the average quality is USD3-4, and the poor quality is about USD 2.50. Such a huge price difference is caused by different stainless steel wire materials. Common stainless steel wire is divided into stainless with nickel, two nickel, nickel-4, 304,304 L, 316,316 L and other materials types.

Different grades of stainless steel wire mesh, nickel content is different. 201 Model among 200 series stainless steel wire mesh has manganese element and low nickel content. Its price is relatively low. This stainless steel is relatively easy to get rust;

304 Model of 300 series stainless steel wire mesh, has only two elements: chromium and nickel. Nickel is generally accounted for 8% ratio, which ensures the stability of this type stainless steel mesh.

As nickel is widely used in industrial elements, and it cost high, so different content raises the price difference. No nickel stainless steel material and two nickel stainless steel mesh are two material types with low-nickel content and easy to get rust. The stainless steel wire mesh made with 4 nickel ss or 304 stainless steel will get rust only encountered strong acid conditions.

To identify stainless steel material with chemical method. Use copper sulfate identification method is more convenient, the effect is obvious. Place a drop of water on the stainless steel mesh, then rub it with copper sulfate. If there is no discoloration, the material is usually stainless steel. If changed into purple, also with non-magnetic, it is usually high manganese steel. The basic difference is only two types of magnetic stainless steel. Because chromium stainless steel can be attracted to a magnet in any state; chrome-nickel stainless steel in the annealed condition is generally non-magnetic after cold working, and some will be magnetic. However, high manganese steel is high manganese non-magnetic; chrome-nickel stainless steel magnetic nitrogen situation is more complicated: some non-magnetic, and some magnetic, some non-magnetic and transverse vertical plane magnetic surface.

Magnet can be used to identify chrome stainless steel and chrome-nickel stainless steel, but it can not correctly distinguish the special nature of some kinds of steel, nor between the specific steel.

Prices can also be a factor identifying the 304 stainless steel wire mesh. The product with low price is basically no 304 stainless steel mesh.
