SS 321H Capillary Tubes Manufacturer, View Weight Chart of Alloy 321 Boiler Tube

Stainless Steel 321 / 321H Tube / Tubing / U Tube is made up of a chromium nickel austenitic stainless steel that is stabilized with titanium. The added titanium element provides extra strength and intergranular resistance to these tubes so that they could operate at up to 900 degrees Celsius and could be welded in the range of 425-850 degrees Celsius with less carbide precipitation. The 321 Stainless steel tube comprises of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel and nitrogen. Nitrogen is absent in the 321H high carbon version. The added titanium depends on the carbon and nitrogen contents of the material. The 321H Seamless Tubes have 515MPa minimum tensile strength and 205MPa minimum yield strength. They also have high brinell hardness of 217. These properties make them good for capillary tubing. The Stainless Steel 321 Capillary tube has very small diameters but can operate with high pressure and temperature conditions.

The capillary tubes are used in thermal applications. There are different standards and specifications such as the din 1.4541 tubing. Each different specification and standard governs certain mechanical properties and dimensions. The SS 321H U tube is a type of tubes used in heat exchangers. Since heat exchangers use the U shape tubes, these are sometimes called the heat exchanger tubes as well. The tubes can range from ½ inches to 100 inches in nominal bore sizes. The electric fusion welded tubes go up to 100 inches while the other types are usually up to 24 inches. The Alloy 321 Boiler tube is used in boilers, super heater elements and in condenser units. We supply all different specifications and standards of the 321 material grade tubes such as the ASTM A484 / ASME SA484 AISI 321. Please contact us to know more about our products.
