ASTM TP321/321H Seamless Stainless Tube Wear and Corrosion Resistance


Zheheng Steel is an excellent supplier of 321/321H stainless steel pipe and other high quality industrial products. The offered ranges of pipes are created as per national and international raw materials quality standards. The industry is offering a comprehensive range of tubes that is varying in standards, dimensions, and specifications. On the request of buyers, the pipes are easily made available at customized specifications. Thus, a buyer can buy the product as per own needs in different sizes, wall thickness, length, diameter etc. The product to all the global and national buyers is supplied at market leading rates.


Stainless Steel 321 Pipes (UNS S32100) is the basic austenitic 18/8 steel (Stainless Steel 304) stabilised by Titanium (321) or Niobium (347) additions. Stainless Steel 321 Tubes is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500 Degree F (427 to 816 Degree C).


The addition of titanium in 321 stainless steel give some desired characteristics:

1.Prevents harmful carbide precipitation in the heat affected zone (HAZ) of the weld area

2.Imparts partial immunity to inter granular corrosion

3.Reduced embrittlement in the HAZ of the weld area


SS 321H Pipes (UNS S32109) is a modification of SS 321 Tubes with a higher carbon content, to provide improved high temperature strength. SS 321H Tubes is the higher carbon (0.04 - 0.10) version of the alloy.



Used in chemical, coal and petroleum industries with high corrosion resistance to grain boundaries, outdoor machines, heat-resistant parts of building materials and parts with difficulty in heat treatment, such as:

1. Oil exhaust gas combustion pipeline

2. Engine exhaust pipe

3. Boiler shell, heat exchanger, heating furnace components

4. Muffler parts for diesel engines

5. Boiler pressure vessel

6. Chemical trucks

7. Expansion joints

8. Spiral welded pipe for furnace pipe and dryer

9. Aircraft
