Some people think that since Stainless steel Perforated sheet is called Stainless steel Perforated sheet, it will not rust, does not contain iron elements, and can be detected for purity by using a strong magnet. They believe that if a strong magnet can attract Stainless steel Perforated sheet, it is a good Stainless steel Perforated sheet, and if it is not attracted, it is a bad Stainless steel Perforated sheet. However, this is not correct. The raw materials used in Stainless steel Perforated sheet are divided into austenitic, martensitic or ferritic types. Austenitic stainless steel includes 304, 321, 316, 310, etc. Austenitic type is magnetically non-magnetic or weakly magnetic. Non-magnetic austenitic type will convert to martensitic structure after secondary cold processing such as punching and bending. Therefore, the raw material of Stainless steel Perforated sheet austenitic type is magnetic. Martensitic or ferritic types are also magnetic, and can be attracted by a strong magnet.

You can use stainless steel identification solution to test the material of Stainless steel Perforated sheet. This method is simple to operate and can be identified within a few seconds. Just drop the stainless steel identification solution on the Stainless steel Perforated sheet surface, and the color of the solution will change. 201 stainless steel shows a deep red, 202 shows red, 301 shows a light red, and 304 shows colorless or pale yellow. This detection method is one of the simplest ways to test the material of Stainless steel Perforated sheet.
