WebMar 29, 2004 · With lower temperature austenitisation less alloy content is dissolved in the austenite (‘underhardening’). Some authorities claim that low temperature austenitisation helps to achieve a higher toughness for tools with hardness levels of 54 - 56 HRC required for hot punching applications. Others claim that best results are obtained by ...

Controlling the Austenite Grain-Size of Steels Metallurgy
WebApr 2, 2024 · However, under abrasion conditions, the homogeneous microstructure of the cast steel is insufficient to achieve the expected service life. The aim of the research is to conduct a comparative analysis of the material in its as-delivered state and after two-stage heat treatment (isothermal annealing followed by re-austenitisation). WebWith increasing austenitisation temperature, the rate of nucleation of austenitic grains increases more intensively than the linear rate of their growth, resulting in a very fine austenite grains, if the holding time there, is very short to avoid the growth. The cooling may be rapid, even by water sprays and the cycle may be repeated.
