304 stainless steel pipe and 201 stainless steel pipe are two of the more popular stainless steel pipe materials in the stainless steel decorative pipe market. So what exactly is the difference between 304 stainless steel pipe and 201 stainless steel pipe?

The main alloy element content difference

Performance differences: due to the different chromium-nickel content and carbon content of the two, 304 stainless steel pipe than the 201 stainless steel pipe is a little softer, and 304 stainless steel corrosion resistance is better.

Application range difference: 201 stainless steel tube acid resistance is poor, mainly used in dry areas and quality requirements are not strict decorative areas, generally used for indoor, dry and ventilated places. 304 stainless steel tube acid resistance is better, can be used in bathrooms, kitchens and coastal wet areas. 201 stainless steel tube is higher manganese content, the surface is very bright, higher manganese content is easy to rust. 304 stainless steel tube contains more chromium, the surface shows Matte, not easy to rust. The two put together obviously different. More importantly, the corrosion resistance is different, 201 stainless steel tube corrosion resistance is very poor, so the price is much cheaper, and because 201 contains low nickel, so the price is lower than 304, so the corrosion resistance is even worse than 304.

Color plating difference: vacuum plating compared to water plating effect is better, but both plating color method will first remove the layer of stainless steel protective film, it is recommended to do electroplating color stainless steel tube with 304 stainless steel material.

Differences in use.

1. Bathroom, kitchen. In life, the bathroom is more humid, the kitchen and more fumes. So these two places must be used 304 stainless steel material to ensure that stainless steel products do not rust.

2. High-rise water supply field. General high-rise water supply system working pressure is very high, and 304 stainless steel pipe tensile strength is very strong, the possibility of leakage in the case of external forces is very small, is the choice of high-rise water supply system.

3. Coastal areas. Due to the coastal areas of the sea breeze, corrosive, choose stainless steel pipe must be selected 304 stainless steel pipe, the use of 201 stainless steel pipe will soon rust.
