ASTM 321 - EN 1.4541

ASTM 321 - EN 1.4541

321 stainless steel strip is a Ni-Cr-Mo austenitic stainless steel alloy. Characterized by increased corrosion resistance at the grain boundaries and improved high temperature strength, 321 effectively suppresses the formation of chromium carbides. In addition, it offers good resistance to atmospheric corrosion.

ASTM 321 - EN 1.4541

Essential details
321/4541 is a titanium-stabilized austenitic stainless steel with improved intergranular corrosion resistance for an extended temperature range. 321/4541 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family. 321/4541 can be welded in all dimensions 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, 321/4541 can be used at elevated temperatures. For high-temperature applications, the use of the optimized high-temperature Therma 321H/4878 is recommended.

321/4541 is available in many product forms and dimensions, often also from many stainless steel stockholders. Polishing of 321/4541 is limited due to its titanium alloying.

Typical Applications:

- Annealing covers

- Stack liners

- Automotive exhaust systems

- Welded pressure vessels

- Flanges and valves
