(1) Commodity: Seamless Stainless Steel Tube/ Seamless Stainless Steel Pipe
(2) Process Method: Cold Drawn / Cold Rolled
(3) Surface Finish: Anneal / Pickling
(4) Main Steel Type & Grade: (a) Austenitic Steel: TP 304/304L/304H/304N, TP310S, TP 316/316L/316Ti/316H, TP 317/317L, TP321/321H, TP347/347H, 904L. (b) Duplex Steel S32205, S31803, S32750.
Description: Type 321 is a standard austenitic 18/8 chromicum 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 9000C.
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 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
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.
