Crafted from titanium-stabilized austenitic stainless steel, our Stainless Steel 321 / 321H Washers are built to last. The Type 321 variant includes titanium to prevent carbide precipitation during welding, ensuring excellent resistance to intergranular corrosion. Meanwhile, Type 321H is a high-carbon version that offers enhanced strength and creep resistance at elevated temperatures. These washers typically contain around 17–19% chromium and 9–12% nickel, boasting good oxidation resistance up to 870°C (1600°F). Both grades maintain their mechanical integrity even under thermal cycling, making them suitable for extended high-temperature use.
You’ll find Stainless Steel 321 / 321H Washers in a variety of applications, from heat exchangers and exhaust systems to furnace components, chemical processing equipment, and aircraft engine parts. They shine in situations that involve frequent thermal expansion and contraction, as well as welding. These washers ensure stable load distribution and maintain joint integrity in assemblies that face heat, vibration, or corrosive environments. With their excellent weldability, heat resistance, and structural reliability, 321 / 321H washers are perfect for industries that demand robust performance in high-temperature conditions.
