ML00171 — Corrosion Fatigue of U Bolt Pipe ClampM - Low Carbon SteelP - BoltAp - ShipCd - Corrosion Fatigue
Detail by scanning electron microscop of the clamp surface showing several cracks, parallel. In this image the cracks appear horizontal, but the photo was taken with the axis of the clamp in the vertical direction which means that the cracks are transverse to the axis.
