Abstract This work describes the hydrogen embrittlement damage of tubing made from a commercial low alloy manganese steel containing vanadium. Hydrogen charging of steels was carried out in 0.5 M H 2 SO 4 solution which contained 10 mg/l As 2 O 3 for 2 h under static load. Fractography was carried out using a scanning electron microscope (SEM) equipped with energy dispersive X-ray spectrometry (EDXS). Normalizing the tubing increased the yield strength. Tubing normalized at 900 °C is more… CONTINUE READING
