SS 321H is a high-carbon variant of SS 321, containing 17-19% chromium, 9-12% nickel, and 0.04-0.10% carbon. The addition of titanium prevents carbide precipitation, enhancing the material’s strength at elevated temperatures. This makes it perfect for environments operating between 800°F and 1500°F (427°C-815°C).
With a tensile strength of 515 MPa (75 ksi) and a yield strength of 205 MPa (30 ksi), SS 321H sheets and plates provide outstanding strength and reliability. Highly fitting for high-stress applications, the Brinell hardness of 217 HB guarantees that the material resists wear and tear. It also provides outstanding formability and weldability, therefore streamlining processing and manufacturing.
