1.4541 Seamless Tubes and 321 SS Exhaust Tubing supplier in India

SA213 TP321 Stainless Steel Tube

SA213 TP321 Stainless Steel Tube

Manufacturers and exporters of SA213 TP321 Stainless Steel Tube in India

The SA213 TP321 Stainless Steel Tube is made of 321 austenitic steel and they are mainly used as heat exchanger tubes. The 321 Stainless Steel Tube is ideal for high-temperature applications, and thus they are used for heat exchangers in different material grades. The specification of 1.4541 Seamless Tubes is for both ferritic and austenitic stainless steel.

The Stainless Steel 321 Heat Exchanger Tubes are known for their heat-resisting properties. They are titanium stabilized and used for various services within a temperature range of 1000 to 1600 degrees F. The Stainless Steel 321 Boiler Tubes generally have good weldable properties, and the addition of titanium in the alloy reduces the formation of carbide precipitation during the welding process. We design the 321 stainless steel exhaust tubing according to the national and international standards of raw material. We follow the set guidelines in the manufacturing process, making the Stainless Steel 321 Fin Tube more durable and safe. The SS 321 Tube also has oxidation resistance to 1600 degrees F. Due to all these properties; the 321 SS Tube has a wide range of applications in exhaust stacks and aircraft piston engine manifolds.

Being one of the top producers of SS 321 Seamless Tube, we offer them at affordable prices. We also offer full customization on the Stainless Steel 321 Tubing solutions, which means we can produce exclusive pieces for the given clients. Purchasing SS 321 Tubing solutions from us, clients will not have to worry about the quality or safety of the products. Our in-house team and third parties conduct several tests to ensure that the 16 Gauge 321 Stainless Steel Pipe is ready for usage. We offer worldwide fast doorstep delivery.

What is ASME SA 213 TP 321 Boiler Tube?

Alloy SS UNS S32100 Helical Tube Heat Exchanger is known to resist polythionic acid stress related corrosion cracking in hydrocarbon applications, and the alloy could also be utilized in caustic solutions free from either chloride or fluoride at moderate temperatures. As typical of this alloy, the ASME SA 213 TP 321 Boiler Tube does not perform well in chloride solutions, even when exposed to small concentrations, or  to sulfuric acid.
