The book "Kraft- und Arbeitsbedarf bildsamer Formgebungsverfahren", by Arno Hensel and Thilo Spittel, edited by the VEB Deutscher Verlag für Grundstoffindustrie (Leipzig), has a rich collection of curves and equations for the calculation of the hot strength of many steels and metallic alloys. However, as you can see from its title, it is written in German.

All the best,
