A conclusion on the WIPANO research project "Safety of Prestressing Steel" was presented in the final committee meeting at the end of the project. The project's exciting findings and recommendations for a new method were discussed with the audience of national and international stakeholders of the prestressing steel industry and representatives of inspection bodies and standardization.
This talk reports the findings of the WIPANO "Knowledge and Technology Transfer via Patents and Standards" research project "Safety of Prestressing Steels," founded by the German Ministry of Economic Affairs and Climate Action (BMWK). A new test method for assessing the susceptibility of prestressing steels to hydrogen-induced stress corrosion cracking (SCC) is presented, which serves the demands of a lower scattering compared with the present standard. Moreover, the ability to differentiate between high susceptible and low susceptible prestressed wires is possible, modifying the method by hydrogen charging and surface preparation.
