Stainless Steel 321 Instrumentation Tube Fittings are made from chromium-nickel austenitic stainless steel that’s stabilized with titanium. This enhancement significantly boosts resistance to carbide precipitation during welding and when exposed to high temperatures. The alloy is known for its impressive mechanical properties, including high tensile and yield strength, good hardness, and exceptional creep resistance. These fittings also exhibit remarkable toughness and dimensional stability, whether in sub-zero or high-temperature applications. Thanks to precision ferrule technology and sturdy construction, SS 321 instrumentation fittings guarantee reliable, leak-tight, and safe connections, even under challenging operating conditions.
