Wear

The following image has been provided by Kevin Sawley, who ran trials of an experimental bainitic rail steel on heavy-haul track in the USA. The steel was had the chemical composition Fe-0.26C-2Mn-1.8Si-1.9Cr-Mo-B. It had an as-rolled hardness of about 415 Brinell and toughness of about 50 MPa m^1/2. The spectacular picture that shows conventional head-hardened pearlitic rail flash-welded to the carbide-free bainitic rail following a trial in which 90 million gross tons of traffic traversed in a sharp curve. The superiority of the carbide-free bainitic rail is fairly clear.
