ASME SA 249 TP 321 Welded Stainless Steel Tubing

ASTM A249 321 Stainless Steel Welded Heat-Exchanger Tubing at lowest price in India

The titanium present in the alloy of ASTM A249 Tp 321 pipes in combination with the carbon content in the metal forms titanium carbide. Being a stable component, titanium carbide is hard to dissolve in steel. This, in turn, aids in the minimization of the occurrence of inter-granular corrosion. Which is why the A249 321 Stainless Steel Welded Tubing inherits its superior welding properties. Thereby proving to be an indispensable alloy grade, especially in those applications which have welding as their primary requirement. The ASTM A249 321 Erw Tubing produced under this specification have to fulfil requirements of not only the chemistry but also mechanical and testing parameters. Hence, the A249 Tp 321 Welded Pipe has a determined grain size while undergoing tests such as reverse-bend test, tension test, flattening test, flange test, hardness test, in addition to a hydrostatic test or if required a nondestructive electric test.
