Production of grinding balls resistant to abrasive wear
WEBSep 23, 2017 · Lowalloy 70KhG chromium–manganese steel is investigated. The thermokinetic diagram of supercooledaustenite conversion at cooling rates –°C/s is plotted. Appropriate heat treatment is developed for grinding balls of diameter 20–60 mm. The microstructure of the steel formed in heat treatment is analyzed. The temperature at .
