HYDROGEN EMBRITTLEMENT RESISTANCE

Notched tensile tests performed in hydrogen and air reveal that 230 alloy is resistant to hydrogen embrittlement.  Tests were performed in MIL-P-27201B grade hydrogen, with a crosshead speed of 0.005 in/min (0.13 mm/min).  Specimens were notched with a KT value of 8.0.
