| Abstract: | The survey of the possibilities for distinguishing between plain carbon steel and chromium-molybdenun steel tubing included the Herber pendulum hardness, magnetic, spark and chemical tests. On the basis of the experiments performed, that of all the methods surveyed the spark test appears to be, at present, the most suitable for factory use from the standpoint of speed, accuracy, nondestructiveness and reliability. It is also applicable for field use. |
