Overwiew:

 

TP321 stainless steel is a Ni-Cr-Mo type austenitic stainless steel, its properties are very similar to 304, but due to the addition of titanium metal, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of titanium metal, it controls the formation of chromium carbide.

 

 

Application:

 

Chemical containers, including for transport

Food preparation equipment particularly in chloride environments.

Coastal architectural panelling, railings & trim.

Chemical containers, including for transport.

Heat Exchangers.
