In previous tests the environment was H/sub 2/S of the highest commercially available purity. In this environment it proved impossible, by our current techniques, to induce hydrogen embrittlement in low yield strength (45 to 75 ksi or 300 to 500 MPa) samples which had been given a post weld heat treatment. The introduction of saturated water vapor in the H/sub 2/S has clearly served to give conditions in which the lower strength steels can be embrittled.
