High strengthened steel bar with elongated pearlite was prepared by caliber rolling at room temperature and its hydrogen embrittlement studied. A 0.6%C - 2%Si 0.2%Mn 1%Cr (in mass%) rolled to a reduction of area 88%, resulting in the evolution lamellar structure similar those cold drawn pearlitic steel. Mean spacing 70 nm texture consisted strong fiber direction parallel <110>. The exhibited hi...
