Capillary Stainless Steel Pipe Tube 304

  According to the definition in GB/T20878-2007, stainless steel is a steel with rust resistance and corrosion resistance as its main characteristics, with a chromium content of at least 10.5% and a maximum of 1.2% carbon content.Stainless steel (Stainless Steel) is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water, or is stainless steel; Corrosion steel is called acid-resistant steel.

  Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally non-corrosive. The term "stainless steel" not only refers to a single type of stainless steel, but also refers to more than one hundred industrial stainless steels. Each stainless steel developed has good performance in its specific application field. The key to success is to understand the purpose first, and then determine the correct steel grade. There are usually only six types of steel related to the application of building construction. They all contain 17-22% chromium, and better steel grades also contain nickel. The addition of molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance of the chloride-containing atmosphere.
