Joint strength was evaluated by testing brazed single-lap joints (SLJs) in tension following standardized procedures. Corrosion tests and microstructural analyses were performed using common practices. In this work, the tradeoff between strength and corrosion resistance of 316L stainless steel joints brazed with a newer “very corrosion-resistant” Ni-Cr-P-Mo-Si BFM and a more established “corrosion-resistant” Ni-Cr-Si-B BFM is quantitatively analyzed. But the spectrum of bold, innovative solutions with stainless steel also encompasses more modern buildings from the second half of the last century which are increasingly falling short of modern requirements.In brazing, the choice of base metal, brazing filler metal (BFM), and braze process conditions involves complex tradeoffs among cost, mechanical strength, corrosion resistance, and others. It includes historic buildings where careful intervention has rescued them from decline and preserved them for future generations. The collection of examples shown in this Euro Inox brochure takes a broad view of the theme New Meets Old. Firmly embedded within this balance between innovation and tradition is stainless steel - in structural applications such as cables or profiles, where its strength allows open, wide-span constructions, and as cladding covering surfaces on the inside and outside of buildings. The challenge of preserving the old while creating the new is giving rise to some exciting new architectural achievements. Stainless Steel in Renovation and Renewal This project was carried out with financial support from the Research Fund for Coal and Steel of the European Community and the International Chromium Development Association.įor more information, please contact Nancy Baddoo at the Steel Construction Institute ( All project reports and a summary report can be found here Five ferritic grades were studied, with varying levels of corrosion resistance (and cost). The project was, in general, limited to developing guidance relevant to these applications involving material less than 6 mm thick in both welded and bolted construction. The SAFSS project, which included material and member testing as well as analytical and numerical studies, provided practitioners with useful performance data and design guidance so that ferritic stainless steels can be specified in structures with confidence.
