Abstract
Tensile tests of an X52 pipeline steel were conducted in air and in hydrogen gas over a range of five orders of magnitude of strain rate. Properties such as elastic modulus, yield strength and ultimate tensile strength were unaffected by hydrogen or by strain rate, while ductility was greatly reduced in hydrogen, compared to in-air, with a moderate effect of decreasing ductility with decreasing strain rate. Different methods of calculating the ductility, from elongation to failure and reduction in area, are discussed as are the consequences of these decisions on the calculated Hydrogen Embrittlement Index.Citation
