Stainless Steel 321 and 321H Instrumentation Tubing is an austenitic stainless steel alloy that’s stabilized with titanium to prevent carbide precipitation during welding and high-temperature applications. Its chemical makeup features chromium and nickel, which provide outstanding corrosion and oxidation resistance. The 321H grade has a higher carbon content, boosting its tensile strength and creep resistance at elevated temperatures. Mechanically, both grades exhibit good ductility, toughness, and the ability to handle pressure, maintaining their dimensional stability and structural integrity even under thermal cycling and continuous use in challenging industrial settings.
