Description

Hydrogen embrittlement was tested in low-alloy Cr-Mo-V steel. Specimens were surface finished and electrolytically charged with hydrogen. Hydrogen was determined by means of a single-purpose EAH 220 analyzer by Balzers. Static tensile tests were used for determining the mechanical properties of the steel hydrogenation. The effect of hydrogen was proven in the tested steel. In tensile specimens with notch, higher sensitivity to contraction within a range of 1 ppm to 2 ppm of hydrogen was shown which was due to the parabolic distribution of stress in the specimens. Jumps around the stress maximum in the stress-elongation working diagram only appeared at high over-saturation above 2 ppm. (M.S.)
