Abstract
An alloy, particularly adapted for the manufacture of railway wheels, and having an improved combination of hardness, and thus wear resistance, plus resistance to thermal cracking in railway wheel applications; the alloy consists essentially of in weight percent, carbon 0.48 to 0.64, phosphorus 0.05 max., sulfur 0.05 max., manganese 0.60 to 1.10, chromium 0.30 to 0.60, nickel 0.50 max., and balance iron.
