WitrynaThere is a balance between hardness and toughness in any steel; the harder the steel, the less tough or impact-resistant it is, and the more impact-resistant it is, the less hard it is. Tempering. The term tempering refers to a heat treatment which is used to increase the toughness of iron-based alloys. Witryna12 gru 2015 · Based on the properties and impact resistance, the optimum levels of Mn and Ni were suggested to be 0.6%—0.9% and 2.5%—3.5% respectively. Additions beyond this limit promoted the formation of segregation structures and other microstructural features, which may be detrimental to weld metal toughness. …
