Improving Hardness and Wear Resistance of Sparingly Alloyed High-Strength Steels for Production of Items Operating under Conditions of Intense Abrasive Wear

This article discusses the structural factors influencing the hardness of steel, as well as the methods of improving the hardness and wear resistance of inexpensive sparingly alloyed high-carbon steels suitable for operation under conditions of abrasive wear and high contact stresses. The mechanism of increasing the hardness by multiple (cyclic) deep cold treatment of martensite hardened high carbon steels is analyzed. It has been demonstrated...
