Patent ID: 7288159

Claim:
A method for manufacturing a fully pearlitic steel rail of high toughness and high wear resistance, consisting essentially of: forging a steel billet comprising the elements in a range from more than 0.9 to 1 .1 wt % of C, 0.26 to 0.80 by wt % of Si, 0.8 to 1.2 wt % of Mn, less than or equal to 0.35 wt % of Cr, the balance of iron and residual elements; hot rolling the billet to a rolling finishing temperature of about 1000° C. and thereby forming a rail; and cooling the rail at a selected cooling rate in a range from 3.3° C./sec to 4.3° C./sec. beginning substantially at said rolling finishing temperature and continuing at least until pearlite transformation-completion temperature.
