Mechanical Tests Specified for ASTM A335 P12 Pipes
| Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test | |
| For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested. | |
| For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe. | |
| Notes for Hardness Test: | P91 shall not have a hardness not exceeding 250 HB/265 HV [25HRC]. |
