摘要：
The comparative effect of molybdenum and chromium on critical points, structure and strength properties of low-carbon pipe steel after different cooling regimes is studied. It is shown that for the basic chemical composition 0.06%C-1.50% Mn-Cu-Nb-Ti addition of chromium and molybdenum leads to a reduction in A(r3) and B-s critical points for hot-worked austenite decomposition. It is noted that with use of the optimum accelerated cooling regime the difference is overcome between the effect of molybdenum and chromium on dispersion of the structure and strength properties of low-carbon pipe steel of the alloy system 0.06% C-1.50% Mn-Cu-Nb-Ti.
