Stainless Steel 321H Pipe Fittings
Stainless Steel 321H is used for different austenitic stainless steel alloy contents with higher additions of titanium and carbon. Addition of titanium allows Alloy 321H to be immune to chromium carbide formation, thus assuring that the alloy performs well in high-temperature environments. This higher carbon modification of Stainless Steel 321 ensures that this alloy has increased strength temperatures at higher ranges as opposed to lower temperature applications.
