Stainless Steel 321 and 321H Instrumentation Tubing contains chromium (17–19%), nickel (9–13%), and titanium for stabilization against intergranular corrosion. Grade 321H features a higher carbon content, enhancing high-temperature strength and creep resistance. Both grades provide excellent tensile and yield properties, good ductility, and stable mechanical behavior under thermal stress. Their strong weldability and resistance to oxidation make them suitable for elevated-temperature operations. Together, these characteristics ensure durable, precise, and reliable tubing for critical instrumentation systems.
