1. Common steels are 304 stainless steel and 201 stainless steel. The main difference between the two is the composition. 304 is of better quality, but the price is also more expensive.
2.201 stainless steel has higher manganese content and less nickel, so it is easy to rust and is cheap. 304 stainless steel contains a lot of chromium, has a variety of processing techniques on the surface, is not easy to rust, and the price is slightly more expensive. The most important thing is the anti-corrosion performance. The anti-corrosion performance of 304 steel plate is good for 201 stainless steel plate. 201 stainless steel contains 15% chromium and 5% nickel. The standard 304 stainless steel contains 18% chromium and 9% nickel.
3. Stainless steel is not easy to rust because the chromium-rich oxide formed on the surface of the steel body can protect the steel body. Material 201 is a high-manganese stainless steel with greater hardness than 304, high-carbon and low-nickel.
4. The main application aspects of the two products are different: 201 stainless steel, with certain acid and alkali resistance, high density, polishing without bubbles, and pinholes, etc. It is a high-quality material for the production of various watch cases and watchband back covers. Wait. Mainly used to make decorative tubes, industrial tubes, and some shallow stretched products. 304 stainless steel has the characteristics of good processing performance and high toughness, and is widely used in industry and furniture decoration industry and food and medical industry.
