When it comes to composition, Stainless Steel 321 Welded Tubing mainly consists of iron, chromium (17–19%), nickel (9–13%), titanium, along with trace amounts of carbon, manganese, and silicon. On the other hand, Stainless Steel 321H has a slightly higher carbon content (0.04–0.10%) to enhance creep strength at elevated temperatures. The titanium stabilization plays a crucial role in preventing carbide precipitation during welding or high-temperature use, offering remarkable resistance to intergranular corrosion. Both grades boast high tensile and yield strength, outstanding toughness, and excellent resistance to creep and thermal fatigue, ensuring they maintain their structural integrity even under extreme conditions.
