Patent ID: 7217329

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 0.7 to 0.95 wt % of C, 0.005 to 0.105 wt % of Ti, 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 such that the rolling finishing temperature is about 1000.degree.C, thereby forming a rail; and heat treating by cooling the rail at a cooling rate in a range from 3.3.degree.C./sec to 4.3.degree.C./sec. beginning substantially at said rolling finishing temperature and continuing to at least 480.degree.C. at which point the rail is released from heat treating.
