    In the eyes of many consumers, there is almost no difference between 201 stainless steel and 304 stainless steel, which can hardly be distinguished by the naked eye. Here are some ways to distinguish them.

    1. Specifications: Commonly used stainless steel plates are divided into 201 and 304 models. Actually, the composition is different. The quality of 304 is good, but the price is expensive, and the difference is 201. 304 is imported stainless steel plate and 201 is domestic stainless steel plate.

    2, 201 composition of 17Cr-4.5Ni-6Mn-N, is a Ni steel grade, 301 steel alternative steel. It is magnetic after cold working and is used in railway vehicles.

    3, 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.

    4, 201 is high in manganese, the surface is very bright with dark bright, manganese is high and easy to rust, manganese is also harmful to the human nervous system, so 201 stainless steel is not suitable for food-grade equipment. 304 contains more chromium, the surface is matte, no rust. The two are put together to compare. The most important thing is the corrosion resistance is different, the corrosion resistance of 201 is very poor, so the price is much cheaper. Because 201 contains low nickel, the price is lower than 304, so the corrosion resistance is not as good as 304. The 304 stainless steel safety is a food grade material. Currently, the food grade stainless steel is 304 stainless steel and above.
