- Abstract
- Studies were undertaken at the National Bureau of Standards to measure the elevated-temperature mechanical properties and to determine the elevated-temperature fracture behavior of selected AAR M128-B steel plates taken from insulated tank car RAX 202. This tank car had been previously tested to failure in a fire environment. Further, these measured elevated-temperature mechanical properties were compared with published data of other plate samples of AAR M128-B steel. A secondary effort was to measure the ambient-temperature mechanical properties of plate samples taken from tank car RAX 202 to determine if the requirements of specification AAR M128-69-B were satisfied.
