Useful Information:

Alloy 321 stainless steel is a titanium-stabilized version of alloy 304, used in particular applications within the sensitizing temperature range. It’s resistance to sensitization, coupled with it higher strength, at high temperatures makes it suitable in application where alloy 304 will become sensitized, or where 304L has insufficient hot strength.

STAINLESS STEEL SS 321
AISI 321
UNS S32100
Werkstoff Nr. 1.4541

Characteristics

  • Excellent resistance to high-temperature corrosion
  • Excellent formability
  • Higher creep resistance
  • Good resistance for intergranular corrosion when expose in midly corrosive environments

Market applications:

  • Chemical & refineries
  • Power plants
  • Super heater and after burner parts
  • Furnace components

These comparisons are approximate only. The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents. If exact equivalents are needed original specifications must be consulted.

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 900°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°C and therefore have its own merits.

Note that Type 321 does not polish well so it is not practical to use this material as cosmetic architectural feature.

Welded Pipe

When selecting a seamless or welded pipe, an abundance of facts should be taken into consideration.

Stainless steel pipes can be manufactured in both seamless or welded forms. The decision whether to use a seamless or welded pipe depends principally on the wall thickness / diameter ratio and the specified pipe tolerances. For the individual production of welded pipes, the raw materials can be ordered and used in precise thicknesses depending on the wall thickness calculations, which will deliberately save resources and cut costs.

Welded pipes are more advantageous for small, medium-sized and large outside diameters with wall thicknesses of between 2 and 70 mm.

Pipe Lengths and Quantities

For welded pipes, the pipe lengths can be freely selected up to 12 m or 18 m without circumferential welds. The minimum production batch for pipes made from coil depends on the length of the coil for special alloys or sizes. With production from individual steel plates, small quantities may also be provided.
