Abstract

1. Use of a steel containing 0.3 to 0.4 % of carbon 0.65 to 1.2 % of silicon 0.55 to 1.3 % of manganese 0.05 to 0.18 % of vanadium 0 to 0.5 % of chromium 0 to 0.2 % of sulphur 0 to 0.1 % of aluminium 0 to 0.04 % of nitrogen, the remainder being iron, and impurities resulting from the melting process, as a material for components which, after cooling in still air, or in moving air, or, if appropriate, after controlled cooling from forging or annealing temperatures above 1,150 degrees C, possess a structure composed of ferrite or pearlite, associated with yield-point values and/or 0.2 % yield-strength values of not less than 490 N/mm2, and absorbed-energy values, measured in notched-bar impact tests on DVM-type test pieces, of not less than 30 J.
