Abstract

The effect of volume–surface quenching (VSQ) by a rapidly moving water flow on the impact toughness at–60°C (KCV^–60) of cast low-carbon 20GL steel, which is used to produce freight bogie solebars, is studied. VSQ is shown to increase KCV^–60 of 20GL steel by a factor of 1.7–2.0 at a higher static and cyclic strength as compared to the normalized state.
