What are the advantages of comparing 201 and 304 stainless steel pipes?

201 stainless steel has the characteristics of certain acid and alkali resistance, high density, no bubbles and no pinholes in polishing. Mainly used for decorative pipes, industrial pipes, and some shallow-stretched products. 201 stainless steel belongs to high manganese and low nickel stainless steel, with low nickel content and poor corrosion resistance. 304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³, also known as 18/8 stainless steel in the industry. High temperature resistance of 800 ℃, has the characteristics of good processing performance and high toughness, and is widely used in industry, furniture decoration industry and food and medical industry. 304 is a general purpose stainless steel that is widely used to make equipment and parts that require a good combination of properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel.

201 decorative stainless steel pipe is much cheaper than 304 stainless steel pipe, and its corrosion resistance and oxidation resistance are not as good as 304 stainless steel pipe. However, 201 stainless steel decorative pipe with strong tube steel is a refined furnace steel belt, and the production of stainless steel pipe is better than that of medium strip steel belt stainless steel pipe. Therefore, many users are willing to choose 201 stainless steel pipe due to its high cost. The high cost is because 201 contains high manganese, the surface is very bright with dark and bright, and the high manganese content is easy to rust. 304 contains more chromium, and the surface is matte and does not rust. The two can be compared together. The important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price is much cheaper. And because 201 contains low nickel, the price is lower than that of 304, so the corrosion resistance is not as good as that of 304.
