When selecting and using stainless steel perforated plates, many users rely on a magnet to determine whether the material is stainless steel. However, this method is not always reliable.
Stainless steel perforated plates mainly come in two categories: austenitic and martensitic types. Austenitic stainless steel (such as 304 and 316) typically does not exhibit magnetism in its natural state, but may develop slight magnetic properties after processing or due to structural changes. Martensitic stainless steel (such as 410 and 420) inherently possesses magnetic properties.
Additionally, some austenitic stainless steels can transform part of their structure into a martensitic phase during stamping or deep processing, causing them to show some magnetism. Therefore, relying solely on a magnet to judge the material of stainless steel perforated plates can lead to incorrect conclusions.

To more accurately identify the material of stainless steel perforated plates, it is recommended to use a stainless steel testing solution. By observing the color change on the surface after applying the testing solution, you can effectively determine the specific material type.
Understanding the material characteristics when choosing and using stainless steel perforated plates is essential to ensure product performance and application effectiveness. Before purchasing, it is advisable to communicate with professional suppliers to obtain detailed material specifications and testing reports, ensuring the product meets your actual requirements.
