STRESS CORROSION OF RAIL WEB STEEL (STATIC)

The test included six rail joint segments containing one bolt hole with a bolt inserted to make the joint. It also included twenty steel specimens taken from rail steel which were subjected to static bending stresses. The twenty corrosion test specimens were tested after nearly twelve and one half years of exposure to the elements. The joint segments were tested approximately one month later. All of the test specimens were cleaned throughly and examined in the laboratory by Magnaflux and Magnaglow methods for the presence of corrosion cracks. While there was considerable pitting to be found, the laboratory examination disclosed no cracks in any of the specimens. This test shows that static stress combined with corrosion has little or no effect upon the development of cracks in rail web steel.
