The commonly used stainless steel plates are divided into two types: 304 and 201, which are actually different in composition. Generally speaking, 304 stainless steel is better in quality, but expensive, and 201 is worse. 304 is imported stainless steel plate, and 201 is domestic stainless steel plate.
304 stainless steel is a common stainless steel, also known as 18/8 stainless steel in the industry, its corrosion resistance is better than 201 stainless steel, corrosion resistance and high temperature resistance, good processing performance, so it is widely used in industry and furniture decoration industry and food and medical industry. , for example: some high-grade stainless steel tableware, bathroom kitchen supplies.
201 stainless steel is austenitic stainless steel. This type of steel has good shape, toughness, weldability and corrosion resistance. It has good corrosion resistance in oxidizing and reducing media. It is used to make acid-resistant equipment, such as corrosion-resistant containers. And equipment linings, conveying pipes, nitric acid-resistant equipment parts, etc.
