Abstract
A wear-resisting surface is produced in artlcles &c. of soft carbon steels containing 0,6-0,8 per cent of manganese and a toughened interior by carburizing the surface until it attains the entectoid composition corresponding to the manganese content, annealing for 10-20 minutes at 10-30 DEG C. above the AC3 point of the initial material and then cooling preferably in still air. The manganese content may be replaced partly by one or more of the metals, chromium, tungsten, molybdenum or vanadium, the manganese content then being 0,5-0,7 per cent and the total content of the other metals about 0,5 per cent. The initial material may contain 0,35-8,0 per cent of silicon or up to 3 of nickel or 1,5 of copper.
