Stainless Steel 321/321H Pipe Fittings are critical components in the construction and maintenance of piping systems, designed specifically from the high-quality alloy, stainless steel 321/321H. These fittings play a crucial role in industries where corrosion resistance, high-temperature performance, and durability are paramount.
Stainless Steel 321/321H Pipe Fittings are integral components in constructing robust and corrosion-resistant piping systems for various industrial applications, offering a reliable solution for the transport of fluids and gases in demanding environments.
The main difference between Stainless Steel 321 and 321H lies in their carbon content. While 321 has a lower carbon content (0.08% maximum), 321H has a higher carbon content (0.04-0.10%). The higher carbon content in 321H provides improved high-temperature strength, making it suitable for applications involving extended exposure to elevated temperatures.
Composition: Stainless Steel 321 typically contains around 17-19% chromium, 9-12% nickel, and 0.08% carbon. It also includes titanium as a stabilizing element. The titanium content provides resistance to carbide precipitation during welding, reducing the risk of sensitization.
Characteristics:
Composition: Stainless Steel 321H is a higher carbon version of 321, containing a minimum of 0.04% carbon. The increased carbon content provides improved high-temperature strength.
