The composition of Stainless Steel 321/321H is distinguished by its titanium stabilization, which provides outstanding resistance to sensitization and intergranular corrosion following exposure to high temperatures. This grade maintains excellent strength and oxidation resistance, making it a robust choice for demanding applications. The “H” variant offers higher carbon content for improved high-temperature strength. These pipes are manufactured through the Electric Resistance Welding (ERW) process, resulting in a product with consistent wall thickness and a superior surface finish, ready for a wide range of industrial uses.
