Abstract

This CWA provides a set of guidelines for the measurement of diffusible hydrogen content in steel sheets, that can be susceptible to hydrogen embrittlement phenomenon. Hydrogen pick up can take place in several processes from steel production, through part manufacturing, till the service life of component. Current risk assessment methods consists in complicated laboratory tests that involve time consuming sample preparation and long test duration. These procedure are not suitable for industrial monitoring where quick, easy and possibly non-intrusive metodologies are required. In this framework, the HELIOS 4 HOT PROBE performs non-destructive diffusible hydrogen measuring method at industrial scale, in order to assess the safe operation of high strength steel parts. The innovative technique allows measurements directly on sheet metal coils and parts, to eventually immediately apply corrective actions in case of process out of control, increasing the safety of the final user.
