Abstract
In the manufacture of railway or tramway rails, the rails are rolled from an alloy steel containing 0.35-0.6 per cent of carbon, about 1 of manganese and 0.30-1.0 of chromium or 1.0-3.0 of nickel, and after leaving the rolls are subjected to an accelerated cooling through the critical range. The temperature of the rails is then equalised at above 500 DEG C. and the rail is then caused to cool slowly from the last-mentioned temperature to about 350 DEG C. The alloy steel may also contain 0.25-1.0 per cent of copper. Specifications 18972/14, 192,446, and 324,686, [all in Class 72, Iron &c.], are referred to.
