Stainless Steel 321H Round Pipes

Stainless Steel 321H Round Pipes have a chemical composition of Iron (Fe) balance, Chromium (Cr) 17-19%, Nickel (Ni) 9-13%, Manganese (Mn) 2%, Silicon (Si) 1%, Molybdenum (Mo) 2-3%, Phosphorous (P) 0.045 max., Sulfur (S)0.030 max., Titanium (Ti) 5x(C+N)-0.70, Carbon (C)0.08 max., and Nitrogen (N)0.10 max. This combination of elements enables the material to create a highly corrosion-resistant alloy that can be used in various applications exposed to regular wear and tear or hostile environments, such as high heat or chloride concentrations. Furthermore, its low carbon content reduces carbide precipitation during welding, while its titanium alloying element provides increased strength at elevated temperatures for applications requiring thermal shock stability.

321H SS Round Pipes can be used in a variety of settings. Due to its excellent corrosion resistance and high-temperature strength, it is ideal for high-temperature applications that require extreme wear and tear or exposure to harsh environments. These large-diameter pipes are well-suited for automotive exhaust systems, chemical and petrochemical process equipment, heat exchangers, pressure vessels, evaporators and condensers, piping systems, and valves. Furthermore, due to their unique properties, such as non-magnetic behavior, superior strength at elevated temperatures, and good weldability, these round pipes are suitable for applications requiring thermal shock stability or operating conditions where there is little maintenance or downtime allowed.
