Design Features -Stainless Steel Seamless Tubes 321/ 321H Grade

  • Immune to intergranular corrosion when heated within the carbide precipitation range.

  • Titanium addition eliminates the formation of chromium carbides at the grain boundaries by tying up the carbon and nitrogen as titanium carbides or nitrides.

  • Better high temperature properties than 304 or 304L. Generally used for parts which are intermittently heated up to 1500°F. For continuous service the alloy is good to 1650°F.

  • May be susceptible to chloride stress cracking.

  • Excellent weldability in the field.

  • Type 321H has a high carbon content (.04 to .10) for better high-temperature creep properties.

Typical Applications - Stainless Steel Seamless Tubes 321/ 321H Grade

  • High temperature chemical process heat exchanger tubes

  • Refineries

  • High temperature steam service
