Semi-hollow punch riveting is essential as a mechanical joining process for the implementation of lightweight construction concepts and mixed construction methods. In order to improve the sustainability of the process chain from forming rivet production to joining, the authors established a new approach in which the use of high-strength, rust-proof rivet materials eliminates the usually necessary heat treatment and coating of the rivet. Since the rivets do not have a coating, which is normally essential for corrosion protection, the corrosion behavior of the new, uncoated rivets made of high nitrogen alloy steel was examined in this article. It was shown that through the targeted selection of a suitable rivet material, higher corrosion resistance can be achieved compared to conventional Almac® or zinc-nickel coatings.
