The Iron and Steel Institute's meeting on "Rail Steels", London, November 23, 1972, is briefly reviewed. The papers were grouped under three headings: "User Experience", Toughness Requirements for Rail Steels" and "New Developments". The first group of papers covered experiences of railroad administrations in five countries on how to optimize the service life of rails and mitigate the effects of cracks, wear, and other defects that can cause premature replacement of rails. A widely accepted need was expressed for a wear-resistant readily weldable rail steel. The second group of papers dealt with the use of fracture mechanics to explain the known facts regarding brittle fracture in a particular set of circumstances and how changes in the properties can in practice decrease the danger of a sudden brittle fracture. The third group of papers dealt with new developments in the field of rail steels in Western Europe. The British approach is to improve fracture toughness and has led to a lower C, higher Mn grain-refined steel. In Belgium a Low-C, low-alloy, Cu-Ni-Cr-Nb steel which will precipitation harden and is readily weldable has been developed. In Germany a rail steel containing 0.7-1.2% Cr with a yield stress in excess of 60 lg/sq mm has been developed to counteract flattening of rail heads and shelling. (A complete report of the proceedings of the meeting is at present out of print.)
