What do we know about Hydrogen Embrittlement (HE)?
A stealthy invader, hydrogen, infiltrates the steel, compromising its integrity and leading to unexpected failures.
Entry of Hydrogen into the Fastener: Occurs predominantly during manufacturing or galvanizing processes, where hydrogen finds its way into the steel lattice.
Diffusion of Hydrogen: Hydrogen atoms diffuse towards regions of high tensile stress within the fastener, driven by the stress gradients.
Hydrogen Segregation: They nestle in grain boundaries, inclusions, dislocations, and other macrostructural traps within the steel.
Reach of Critical Hydrogen Concentration: Accumulation of hydrogen reaches a critical concentration, setting the stage for potential catastrophic failure.
Prevention and Hydrogen Relief: Employing rigorous manufacturing practices and postproduction treatments to minimize hydrogen ingress and promote its escape.
Inspection Procedure: Employ meticulous inspection protocols to detect and measure ΗΕ, ensuring the reliability of the fasteners
