Stainless Steel 321 Tubing is a top-notch austenitic stainless steel product crafted for situations where outstanding corrosion resistance, high-temperature strength, and long-lasting durability are essential. Thanks to its titanium stabilization, 321 tubing effectively combats intergranular corrosion, making it a perfect fit for boilers, heat exchangers, chemical processing equipment, and industrial piping systems that face high temperatures and tough chemical conditions.
This tubing is mainly made up of iron, chromium, nickel, and titanium. The chromium gives it impressive corrosion resistance, while nickel boosts its toughness and ductility. Titanium plays a crucial role in stabilizing the microstructure, ensuring that the tubing maintains its mechanical integrity even at elevated temperatures. With its remarkable tensile strength, thermal stability, and resistance to creep, this tubing is well-suited for high-stress and high-temperature applications.
