The hydrogen induced delayed fracture of ultrafine grained 0.6% O steel with dispersed oxide particles was discussed. The MM of 0.6% O steel powder followed by consolidation at 700 °C resulted in the ultrafine grained steel having an average ferrite grain size of 0.3 μm and the dispersion of Cr 2O3 particles of 10 nm. It was found that the grained steel exhibit high resistance to hydrogen embrittlement at the tensile strength of 1300 MPa by hydrogen trapping effect related to the nanosize oxide particles.
