What is the SS 321 Pipe?
SS 321 pipe is a popular metal with numerous applications and uses. We will also explain its different grades and the differences between them. After reading this article, you will be able to choose the right one for your needs. This metal is perfect for structural applications, particularly those that require higher temperatures.
Applications of SS 321 Pipe
SS 321 Pipe is a high-quality material that meets the needs of a wide range of industrial processes. Its superior weldability is one of its main advantages, which makes it the material of choice for many industries. This steel has excellent heat resistance without compromising on other mechanical properties, such as toughness. It can resist corrosion and oxidation at high and low temperatures. Most industries prefer this steel over Type 304, which has the disadvantage of proneness to stress corrosion cracking.
Type 321 steel is susceptible to stress corrosion cracking in halides. This stainless steel is similar to Type 304 in nickel content, and it exhibits several of the same conditions that lead to stress corrosion cracking. These conditions include the presence of a halide ion, environmental temperatures over 120deg F, and residual tensile stresses. Residual tensile stresses result from thermal cycles and cold deformation, but they can be reduced by annealing. However, this stainless steel is not recommended for use in marine environments.
