SS 321 Pipes are austenitic chromium-nickel stainless steel pipes that have been
stabilized with titanium. Stainless Steel 321H Pipes
are variants of
Stainless Steel 321 Pipes with high carbon content.
The high carbon content of this alloy provides added strength to the steel. This
titanium addition provides greater resistance to intergranular corrosion. The
addition of titanium also improves the tensile strength of the SS 321H Tubing.
Moreover, the tubing is more resistant to higher temperatures. Its titanium
content makes it suitable for higher temperature environments up to 900C.

There are several grades of pipes which includes
Stainless
Steel 304 Pipes, Stainless Steel 347 Pipes, Stainless
Steel 316Ti Pipes, etc.
The 321H Stainless Steel Pipes are known for their high creep resistance and
enhanced corrosion resistance. These UNS S32100 Pipes and 321H SS
Pipes are utilized often in operating temperature environments above 500° C
and have good welding and forming capabilities. Grade 321 has excellent forming and
welding capabilities. It is resistant to many organic chemicals, inorganic
chemicals, and sterilizing solutions. Stainless
Steel 321H Seamless Pipes have good oxidation and scaling
resistance. It is suitable for use in all standard welding techniques. It has
excellent resistance to most diluted organic acids and chlorides at moderate
temperatures.

SS 321H Industrial Pipes are highly recommended for a variety of industrial
applications. It is also used for heavy-duty exhaust systems and boiler Pipes. These metals
have the added benefit of being able to resist the corrosive effects of chloride-free
caustic solutions at moderate and high temperatures. SS 321H Pipes are used in general
refinery piping, heavy-duty exhaust systems, boiler Pipes, and radiant superheaters. It is
stabilized with titanium to prevent carbide precipitation. These pipes can be used in
chloride-free caustic solutions at moderate temperatures.
