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
-
