How to distinguish between 201 and 304 stainless steel wire mesh with the naked eye?

201 stainless steel wire mesh C: ≤0.150, Si: ≤1.00, Mn: ≤8~11, P: ≤0060, S: ≤0.03 0, Ni: 0.9-1.5, Cr: 15-17, N: 0.200, Cu: 1.5-2. It can be seen that the 201 stainless steel wire mesh contains high manganese, and the surface is very bright with dark and bright. Because of the high manganese content, it is easy to rust; 304 stainless steel wire mesh Cs0.08, Sis1.00, Mns2.00, P< 0.045, Ss0.030, Ni: 8.00-11.00, Cr: 18.00-20 00, it can be seen that 304 contains more chromium, so the surface is matte. Because 304 stainless steel wire mesh contains nickel, it is not easy to rust. The stainless steel wire mesh of the two materials can be distinguished by the naked eye when put together.

The composition of 201 is 17Cr-45Ni-6Mn-N, which is an alternative to Ni-saving steel grade and 301 steel. After cold processing, it has magnetism and is used in railway vehicles. The composition of 304 is 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. 201 stainless steel wire mesh belongs to high carbon and low nickel, which is harder than 304 stainless steel wire mesh, but its toughness is not as good as 304. The fatigue resistance of 304 stainless steel wire mesh is better.

At present, two types of stainless steel wire meshes of 201 and 304 are commonly used. The two materials are only different in composition. 304 stainless steel wire mesh is of better quality and slightly more expensive, while 201 is less expensive. 304 stainless steel wire mesh is widely used in the production of corrosion-resistant and formability equipment and parts due to its good heat resistance. At present, 304 stainless steel has been widely used in food, chemical, atomic energy and other industrial equipment and decoration fields.
