As a specific grade among austentic stainless, and although especially difficult to process, 21.6.9 has a yield strength double that of other steels within the same family and includes a higher Chromium content. Both assets, lightness and corrosion strength, provide it with a special status in the aeronautical field where it is widely used. SPÉCITUBES cold draws 21.6.9 welded tube hollows to optimise the required performance/weight ratio through achieving thin wall thickness. Experience and know-how make 21.6.9 SPÉCITUBES products highly reliable.
References abound from Europe as well as from the Americas.
