Cyclic Deformation Behaviour of a Fe-28Cr-4Mo-2Ni-0.43Nb Superferritic Stainless Steel
Abstract
The alloy studied in the present investigation is a superfe-rritic stainless steel which is characterized by a high pitting and corrossion resistance in aggressive environments such us polluted sea water (1,2). In order to achieve better ductility and intergranular corrosion resistance in relation to the conventional ferritic stainless steels of high Cr content, the total amount of interstitial elements in this new family of superferritic stainless steels is kept very low (C+N≤0.01%). The amount of interstitial elements in solution in such alloys produced by the V.O.D. technique, as in the present case, has to be lowered by the addition of small amounts of Nb and Ti to form carbonitrides, which take out carbon and nitrogen from solution.
