Stainless Steel 321 Pipes and Tubes Overview
Stainless Steel 321, also known as UNS S32100 and DIN 1.4541, has some titanium to stabilize carbon and inhibit the formation of carbides during welding or even when subjected to high temperatures. This feature renders 321 stainless steel pipes and tubes to be applicable in fabrication areas that have limited or impractical post-weld heat treatment. The grade has good resistance to oxidation and scaling in high temperature and still has corrosion resistance characteristics of austenitic stainless steels.
In high-temperature processes using piping system with high precision of dimensions, stainless steel 321 tubes have been used with fittings that match the tube in order to achieve leaks free assembly. To connect instrumentation and process You can use our stainless steel 321 tube fittings which are designed with the purpose of maintaining a uniform OD and ensuring the integrity of joints.
When it comes to applications in which a higher temperature alloy is required than austenitic stainless steels, procurement departments are also able to consider nickel-based alloys in applications where such alloys are employed. Incoloy 800 pipes and tubes are often used in combination with SS 321 in order to select certain service conditions.

Frequently Asked Questions on Stainless Steel 321 Pipes & Tubes
Stainless Steel 321 pipes are used in high-temperature and cyclic heating applications where resistance to intergranular corrosion is critical. Typical uses include heat exchangers, exhaust systems, refinery piping, and thermal processing equipment operating above 425°C.
SS 321 contains titanium stabilization, which prevents carbide precipitation during welding or high-temperature service. SS 304 does not have this stabilization, making SS 321 pipes more suitable for welded high-temperature applications.
Stainless Steel 321 pipes are commonly manufactured to ASTM A312 TP321 for seamless and welded pipes, and ASTM A213 TP321 for heat exchanger and boiler tubes. Dimensional standards typically follow ASME B36.19.
Yes. SS 321 pipes offer excellent weldability without requiring post-weld heat treatment in most cases. Titanium stabilization minimizes the risk of intergranular corrosion in welded joints exposed to elevated temperatures.
Stainless Steel 321 is available in seamless, ERW, EFW, and welded pipes, as well as round, square, rectangular, and heat exchanger tubes, supplied in multiple schedules and wall thicknesses based on application requirements.
SS 321 pipes can typically operate in continuous service up to 870°C and intermittent service up to 925°C, making them suitable for high-temperature process lines, furnace components, and thermal systems.
Yes. Stainless Steel 321 pipes supplied by Aashish Metal and Alloys are delivered with Mill Test Certificates (EN 10204 3.1) and optional third-party inspection documents based on project and export requirements.
