Grade A249 TP321 is one of the stainless steel alloys designed for high temperature applications. Specifically, this ASTM
specified A249 TP 321 grade is typically used for piping systems involving superheaters, boilers, heat exchangers,
or condensers. Stainless Steel 321 Erw is a titanium alloy grade. Titanium is often added to carbon steel grades with higher
carbon content, such as ASTM A249 Tp321, to stabilize carbides.
ASTM A249 321 Stainless Steel Welded Heat Exchanger Tubes The titanium in ASTM A249 TP321 pipe alloy combines with the carbon content of the metal to form titanium carbide.
As a stable component, titanium carbide is difficult to dissolve in steel. This in turn helps minimize the occurrence of
intergranular corrosion. This is why A249 TP321 stainless steel welded pipe inherits its excellent welding performance.
Therefore, it has proven to be an indispensable alloy grade, especially in those applications where welding is the main
requirement. ASTM A249 TP321 Erw tubing produced to this specification must meet not only chemical requirements,
but also mechanical and testing parameters. Therefore, A249 TP321 welded pipe has a defined grain size when subjected
to reverse bending, tensile, flattening, flange, hardness, etc. tests, in addition to hydrostatic pressure testing or non-destructive
