Specifications

Stainless Steel Seamless Pipe:  
1. Material: TP321
2 OD: 6 - 830MM, THICKNESS: 0.6 - 60MM
 
Type 321 is a standard austenitic 18/8 chromium nickel alloy with the addition of Titanium
making it an excellent choice in elevated temperature environments.
 
The titanium stabilises the material removing its susceptibility to the effects of intergranular
corrosion. 321 is therefore the stainless steel material of choice for applications in working
environments up to 9000 C.
 
A drawback of Type 321 is that the titanium does not transfer well across a high temperature
arc, so it is not recommended as a welding consumable
In such instances, 347 is the preferred choice as the Niobium performs the same function as
Titanium but can be still transferred across a high temperature arc. Type 347 is therefore the
consumable of choice for welding Grade 321.
 
The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures. If you are looking
for a stainless steel to provide resistance to intergranular corrosion, 304L is the normal choice as it is a more commonly used
and supplied steel
However, 321 is a much better option in operating temperature environments in excess of 500
0C and therefore have its ownmerits.
Note that Type 321 does not polish well so it is not practical to use this material as cosmetic architectural feature.
