General characteristics
Core 321/4541 is a titanium-stabilized austenitic stainless steel with improved intergranular corrosion resistance for an extended temperature range. 321 / EN 1.4541 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family. 321 / EN 1.4541 can be welded without becoming susceptible to intergranular corrosion.

The austenitic CrNi standard grades are the most widely used group of stainless steels. 
Their well-balanced material properties make them suitable for the fabrication of many products. 
Due to its titanium content, 321 / EN 1.4541 can be used at elevated temperatures. 
For high-temperature applications, the use of the optimised high-temperature 321H / EN 1.4878 is recommended.
321 / EN 1.4541 is available in many product forms and dimensions, 
Polishing of 321 / EN 1.4541 is limited due to its titanium alloying.


Typical applications
Annealing covers
Stack liners
Automotive exhaust systems
Welded pressure vessels
Flanges and valves
