gnostek1 / 4Hydrogen-induced cracking (HIC) [ clarification needed ]
- 01Hydrogen atoms are small enough to diffuse through solid steel at room temperature without any visible entry point.
- 02High-strength steels above 1,000 MPa yield strength are most vulnerable — the stronger the steel, the worse the risk.
- 03The 2013 San Francisco Bay Bridge bolt failures were caused by hydrogen embrittlement in A354 grade rods.
