304 stainless steel is a kind of universal stainless steel material, the antirust performance is stronger than 201 stainless steel material. Resistance to high temperature also is better, generally use temperature limit of 650 ℃. 304 stainless steel has excellent rust resistance and intercrystalline corrosion resistance. Therefore, 304 stainless steel is widely used in medical equipment and food utensils, and the harm to human body is minimal. 201 stainless steel, with a certain acid and alkali resistance, high density, no bubble after polishing, no pinhole and other characteristics, is the production of a variety of watch case, watch band bottom cover quality materials. Mainly used for decorative pipe, industrial pipe, some products with shallow stretch. 201 is nickel - saving steel, high - manganese, surface very bright, with dark light, high - manganese rust. 304 contains a lot of chromium, the surface appears matte, do not rust. The most important thing is that the corrosion resistance is different, the corrosion resistance of 201 is very poor, so the price is much cheaper. Because of the low nickel content of 201, the price is lower than that of 304, so the corrosion resistance is not as good as that of 304.
