409 stainless steel is a ferritic steel recognized for its good mechanical properties and corrosion resistance. It contains 11% chromium, which is the minimum amount required to form the passive surface film that makes stainless steel corrosion-resistant.
409 Stainless Steel Pipe Description
The chemical composition of 409 stainless steel pipes sets it apart from other stainless steels. It is mainly comprised of iron, with large amount of chromium and small amounts of carbon, manganese, silicon and nitrogen. Iron is the main element of 409 stainless steel, making for its strength and stability. Chromium helps form a protective oxide layer on the surface to ensure corrosion resistance. Carbon adds to the material's hardness and wear resistance. Manganese acts as a stabilizer to prevent excessive grain growth during heat treatment. Silicon enhances oxidation resistance while minimizing scaling at high temperatures. Nitrogen improves mechanical properties such as tensile strength and yield strength. This unique combination of elements gives 409 stainless steel excellent thermal expansion capabilities, making it suitable for high-temperature applications without jeopardizing its structural integrity or dimensional stability. Its chemical composition also helps achieve good solderability, thus simplifying the manufacturing process.
