What is Pinetown Bolt Failure Analysis Report about?

The document summarizes a metallurgical investigation into a failed hold-down bolt. Testing found the bolt failed due to hydrogen embrittlement. The bolt had a tensile strength over 1000 MPa, making it susceptible. Hydrogen embrittlement likely occurred during acid pickling before galvanizing. Microscopic analysis showed brittle cleavage fracture confirming hydrogen embrittlement as the cause of failure when the bolt was being straightened.
