The ferritic stainless steel seamless pipe and tube is a stainless steel seamless pipe with a ferritic structure as the mainstay in the use state. The chromium content is between 11% and 30%, and it has a body-centered cubic crystal structure.
This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance. It is mostly used to manufacture parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion.
This kind of steel has disadvantages such as poor plasticity, significantly reduced plasticity and corrosion resistance after welding, which limits its application. The application of refining technology outside the furnace can greatly reduce interstitial elements such as carbon and nitrogen so that this type of steel has been widely used.
If you need to buy various kinds of stainless steel seamless pipes such as austenitic stainless steel seamless tubes, Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. will be your good choice.
