Abstract
A railway wheel, comprising a rim connected to a hub by a flange which is less thick in the axial direction than the rim, is made of steel containing less than 0.35% carbon and less than 5% in total of alloying elements has an Ms point above 270 degrees C. During manufacture it is tempered and then heated at over 550 degrees C, so that at least the outer surface of the rim has mechanical properties as follows: Rm=860-960 MPa, Rp 0.2 at least 700 MPa, K1c at least 80 MPa per square m. Also claimed is a wheel of this sort, made of steel containing by weight 0.2-0.24% carbon, 0.9-1.1% manganese, 0.9-1.1% silicon, 1-1.2% chromium and 0.2-0.25% molybdenum, the rest being iron and impurities. The wheel has the mechanical properties listed above which are not affected by braking equivalent to 540 degrees C maintained for one hour.
