　　Due to the corrosion resistance and environmental protection of stainless steel pipe, the market has a great demand for it. But many people often confuse stainless steel pipe with carbon steel pipe.

　　Carbon steel pipe can also be called carbon steel pipe, such as common Q195, Q235. Carbon steel can also be called magnetic alloy steel, except for carbon and iron, there are no other metal elements. Stainless steel is chromium nickel steel. In addition to carbon and iron, there are other metal elements such as chromium, nickel and copper. When the chromium content in the steel pipe exceeds 12.5%, a protective film will be formed on the surface of the steel pipe, so as to achieve the effect of corrosion resistance. So the main difference between the two is corrosion resistance, carbon steel pipe is easy to rust, and stainless steel pipe is corrosion resistance steel.

　　The elements between carbon steel pipe and stainless steel pipe are different, so they play different roles and are applied in different fields.
